History Main / BossArenaUrgency

** Suverted in ''VideoGame/MegaMan2'' against the second Wily Stage boss, Picopico-kun. It only ''appears'' the boss is making holes in the arena, but they're perfectly solid.

Note that many bosses will become progressively tougher and switch to stronger attacks as the battle wears on; while BossArenaUrgency may overlap, this isn't always the case. For example, if this progression only occurs after inflicting specific amounts of damage, then this is simply because the boss TurnsRed; BossArenaUrgency occurs if this progression takes place ''independently'' of the player's actions.

** ''[[VideoGame/SonicRushSeries Sonic Rush and Sonic Rush Adventure's]]'' penultimate fights both end with this. After your FreeFallFight with Eggman/Nega in the former sinks below the clouds, he'll ram his mecha into the stage, destroying it if you don't hit him. After hitting Captain Whisker enough times in the latter, he'll instead fire [[LastDitchMove two extremely powerful lasers]] [[AdvancingWallOfDoom that close in on you.]] If you don't hit him when he gets close enough, you'll be [[OneHitKill obliterated]].

** In ''[[VideoGame/MegaManX4 X4]]'', there's the mid-boss of Split Mushroom stage, Tentoroid. Thankfully, it only takes a few charge shots to destroy, but if you're going for a no charge shot run like a certain [[LetsPlay/RoahmMythril dragon]] and his X-series equivalent LetsPlay/{{Kevvl}} do, it's pretty tough to land enough shots before [[SpikesOfDoom spiky]] doom. [[http://www.youtube.com/watch?v=fioXsT65Zq0 Kevvl did pull it off, though]].

** The TrueFinalBoss of ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'', and some of the 3D games (including the aforementioned ''Sonic Adventure'',) is like this. You don't have an actual timer, but you start the fight as [[SuperMode Super Sonic]]. If you run out of rings, you turn back to normal, and in the boss fight, this causes you to die. This makes sense in S&K, as the fight takes place in space, but makes less sense in Sonic Adventure, where you could, hypothetically, run out of rings on a floating piece of road, but the game assumes you fell into the water and drowned regardless.[[note]]Probably because if you're not Super, you can't do jack to the boss, even if you ''did'' coincidentally land somewhere marginally less deadly.[[/note]]

* In ''VideoGame/{{Ys}} I'', everytime you hit Dark Fact, a piece of the platform drops out. If you're standing on said piece, you die instantly. If you aren't leveled up enough (in the TurboGrafx16 version, that is; in others you'll already be at the {{cap}}), you'll end up with too many holes and become trapped and killed.

** Suverted in ''[[VideoGame/MegaMan2]]'' against the second Wily Stage boss. It only ''appears'' the boss is making holes in the arena, but they're perfectly solid.
* In ''[[Creator/{{Taito}} Panic Restaurant]]'', the boss of the refrigerator level is a giant evil ice cream who breaks the ice-cube floor with its cone.

* The final boss in Shatterhand (NES) has a move that breaks away part of the floor, turning it into fire. it isn't an instant kill, but it does constant damage and you recoil from hits, thus making it part of this trope.

* In ''VideoGame/PanicRestaurant'', the boss of the refrigerator level is a giant evil ice cream who breaks the ice-cube floor with its cone.

* In her second-to-last form, the [[BigBad GoldenDiva]] of ''VideoGame/WarioLand 4'' starts smashing the floors of her arena. Miss too many chances to damage her, and you'll have nothing to stand on but spikes. Which are painful.

** A few games later, ''VideoGame/YsVITheArkOfNapishtim'' gives us boss 3, Ud-Meiyu, whose most common attack, a jumping stomp, knocks out the floor panels over the deadly lava under the arena.

** In ''[[VideoGame/MegaManX4 X4]]'', there's the mid-boss of Split Mushroom stage, Tentoroid. Thankfully, it only takes a few charge shots to destroy, but if you're going for a no charge shot run like a certain [[LetsPlay/RoahmMythril dragon]] and his X-series equivalent Kevvl do, it's pretty tough to land enough shots before [[SpikesOfDoom spiky]] doom. [[http://www.youtube.com/watch?v=fioXsT65Zq0 Kevvl did pull it off, though]].

** Another ''Sonic'' example: the Egg Golem from ''VideoGame/SonicAdventure2''.
** SonicRush and SonicRushAdventure's penultimate fights both end with this. After your FreeFallFight with Eggman/Nega in the former sinks below the clouds, he'll ram his mecha into the stage, destroying it if you don't hit him. After hitting him enough times in the latter, he'll instead fire [[LastDitchMove two extremely powerful lasers]] [[AdvancingWallOfDoom that close in on you.]] If you don't hit him when he gets close enough, you'll be [[OneHitKill obliterated]].

** Wario Land 1 has the big giant head that shoots rock boogers out of his nose and licks rocks. ...erm... It's this trope.
* VideoGame/YoshisIsland: The [[BackgroundBoss final boss]] will start off by occasionally dropping boulders near where Yoshi stands, leaving sizable gaps. When he's about to die, he bum-rushes the arena to destroy all platforms and knock Baby Mario out of the saddle while Yoshi plummets. Pretty much screwed either way.

Compare TimeLimitBoss, StalkedByTheBell and IncreasinglyLethalEnemy. Contrast BossArenaIdiocy and its close cousin HoistByHisOwnPetard.

* In ''VideoGame/AzureStrikerGunvolt'', when you bring the final boss [[OneWingedAngel Nova's]] HP down to one-third, he uses a super attack that causes a meteor to come down directly above you, [[DescendingCeiling lowering your room to maneuver]]. Touch it by taking too long to win the fight or jumping into it, [[OneHitKill you die instantly]], and have to fight the boss' previous form all over again.

* ''VideoGame/{{Bastion}}'' : Some of the larger ememies weild giant pickaxes that they attempt to hit you with. Sometimes they'll show up in the more unstable areas and take out chunks of the floor with each hit. They have low enough health that it's rare for them to take out an entire fighting space, but those holes they punch make it much harder for you to move around when you're being swarmed by smaller enemies. Most of whom can hover right over the holes no problem.
* In ''VideoGame/EccoTheDolphin: Defender of the Future'', the final boss is the alien queen's [[WombLevel heart]]. During the fight, blood rises from the bottom. if you don't defeat it quickly, Ecco will drown in the blood. [[JustifiedTrope Which makes sense]] because blood doesn't have air in it, and dolphins [[TruthInTelevision being mammals cannot breathe in any liquid whatsoever]].
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'': The fight against Ganondorf takes place in the top room of a tower, with Ganon in the middle and you standing on platforms along the edge. One of his attacks will know some of the platforms down, but the platforms in the corners are permanent. Downplayed, in that falling off simply sends you to the ground below from which you can climb back up.

* ''VideoGame/MonsterHunter'': Say hello to Dalamadur, the only boss in the series to destroy the arena you are fighting him to limit you movement. In this series that is a VERY bad thing.

* The final boss of ''VideoGame/SnowBros'' arcade is a very interesting example. There are two giant stone heads on each side of the screen, a small platform surrounded by flames in the middle and a descending ceiling full of spikes right above that. The heads continuously blow bubbles which can have enemies or power-ups inside, and these pop if they touch the spikes. The player has very little space to move, and the more the ceiling goes down, the faster the enemies can get him... of course, this also means that he can throw many more snowballed enemies against the heads, but he is forced to think and act much more frantically.

* In ''Chains of Promathia'', the second expansion of ''VideoGame/FinalFantasyXI'', you have the fight against Diabolos. In addition to the standard time limit for any bossfight, you also have to contend with a floor that falls away, except for a number of panels which never do. The pit below isn't bottomless, it's simply filled with giant spiders.

** In ''[[VideoGame/MegaManX4 X4]]'', there's the mid boss of Split Mushroom stage, Tentoroid. Thankfully it only takes a few charge shots to destroy, but if you're going for a no charge shot run like a certain [[LetsPlay/RoahmMythril dragon]] and his X-series equivalent Kevvl do, it's pretty tough to land enough shots before [[SpikesOfDoom spiky]] doom. [[http://www.youtube.com/watch?v=fioXsT65Zq0 Kevvl did pull it off, though]].

*** The Carnival Night Act 1 mid-boss encountered earlier in the game also applies, as the elevator you're on gets broken up by the spinning top the boss deploys when you enter the room. You need to hit the boss (preferably when it's not electrocuting itself) to expose it's core for the top to damage it (it only takes four hits rather than six or eight.)

** ''VideoGame/SonicAdventure'''s Egg Viper will, near the end of the fight, start destroying the flooring. This happens when it's taken five hits, before then you can take as long as you want. After that, though, you'd better have at least two platforms left when you beat it, as it'll make a suicide dive for where you're standing that will destroy at least one of them.

** The TrueFinalBoss of ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'', and some of the 3D games (including the aforementioned ''Sonic Adventure'',) is like this. You don't have an actual timer, but you start the fight as [[SuperMode Super Sonic]]. If you run out of rings, you turn back to normal, and in the boss fight, this causes you to die. This makes sense in S&K, as the fight takes place in space, but makes less sense in Sonic Adventure, where you could, hypothetically, run out of rings on a floating piece of road, but the game assumes you fell into the water and drowned regardless.[[note]]Probably because if you're not Super you can't do jack to the boss even if you ''did'' coincidentally land somewhere marginally less deadly.[[/note]]
** Another ''Sonic'' example: the Egg Golem from ''VideoGame/SonicAdventure2''..

** Wario Land 1 has the big giant head that shoots rock boogers out of his nose and licks rocks. ... erm ... It's this trope.

* In a rare RealTimeStrategy example, the final mission of ''VideoGame/StarcraftIILegacyOfTheVoid'', has god-like superbeing Amon periodically annihilating parts of the map... namely, the resource deposits you build your bases on. You'd better have mined them out before he gets there, because once they're gone they're not coming back. Take too long, and you'll have no resources left at all to complete the mission.

* ''VideoGame/AlienSoldier'' had "Back Stringer". You fought this GiantSpider on the wings and body of its dinner, a [[http://www.bogleech.com/aliensoldier/as-spiderbattle.gif decapitated giant fly]]. Small destructible [[DemonicSpiders spiders]] would come up from the bottom of the screen and pull the fly down the big spider web (each additional one making it sink faster). If the fly platform disappears off the bottom of the screen, expect to [[GameOver die]]- you'll keep falling into a [[NonLethalBottomlessPits health-draining bottomless pit]] [[CycleOfHurting OVER AND OVER AGAIN!!!]]

[[AC:FightingGame]]
* [[VideoGame/PunchOut Mike Tyson]] destroys your platform in ''VideoGame/IWannaBeTheGuy''.
** So does TheGrimReaper in ''VideoGame/IWannaBeTheFangame''.

* The TrueFinalBoss of ''[[VideoGame/GargoylesQuest Demon's Crest]]'' throws orbs that steadily turn parts of the walls and floor into damaging spikes. Your character can fly, but midair maneuverability is ''very'' limited.
** On the other hand, in order to encounter this boss, you must first acquire the ability to spit a type of fireball onto wall spikes that makes them temporarily safe to land on, so it's still merely inconvenient rather than inevitably lethal.

The difficulty of these bosses is [[UnstableEquilibrium directly proportional]] to how long it takes to defeat them: If you've played the game repeatedly or are quick enough to get a few attacks in early, the boss is hardly a challenge; but if the fight drags on for a long time, he'll become a nightmare to defeat -- if it's [[{{Unwinnable}} still possible to defeat him at all]] -- and may be a candidate for ThatOneBoss.

[[caption-width-right:250:Can you ''please'' stop trying to punch holes in the flooring?]]

* The ''Franchise/SonicTheHedgehog'' series has several.
** [[VideoGame/SonicTheHedgehog Spring Yard Zone's]] boss has a spike on its base, and one by one removes the bricks that make up the floor of the arena; this continues until you defeat the boss, or lose all your footing and fall down the BottomlessPit below.
*** Or defeat the boss, and then [[KaizoTrap carelessly tumble to your death as you go to exit the stage]]. [[YetAnotherStupidDeath Yep.]]
** The boss in ''VideoGame/Sonic3AndKnuckles'''s Sandopolis Act 2 will slowly make its way from the right side of the room to the left. If you take too long, the boss will pin you against the left wall and make the fight unwinnable.
*** Playing as Knuckles? Enjoy the boss moving about twice as fast, which also means that much less time to use his hand as a platform. Actually quite tough, though you can exploit Knuckles' gliding to stunlock the boss once you can get up there.
*** The Carnival Night Act 1 mid-boss encountered earlier in the game also applies, as the elevator you're on gets broken up by the spinning top the boss deploys when you enter the room. You need to hit the boss (preferably when it's not electrocuting itself) to expose it's core for the top to damage it (it only takes four hits rather than six or eight.)
** ''VideoGame/SonicTheHedgehogCD'''s semifinal boss fight has Sonic and Metal Sonic race. If you're too slow, you get hit by the only instant-death laser in the entire Genesis era, and if Metal Sonic wins the race, you're doomed.
*** And while it is very hard to invoke such a thing, this can also happen in Tidal Tempest's boss. As the screen is totally submerged and the only source of air is the barrier around Eggman's machine, if the air barrier is totally depleted, Sonic must defeat Eggman to drain the area of water before he drowns.
** ''VideoGame/SonicAdventure'''s Egg Viper will, near the end of the fight, start destroying the flooring. This happens when it's taken five hits, before then you can take as long as you want. After that, though, you'd better have at least two platforms left when you beat it, as it'll make a suicide dive for where you're standing that will destroy at least one of them.
** ''[[VideoGame/SonicTheHedgehog2006 Sonic 2006]]'''s Egg Wyvern tries to emulate this, but it tends to only destroy parts of the arena after reaching certain damage thresholds, [[SubvertedTrope making it]] more of a case of TurnsRed instead.
*** There's also the final fight with Iblis, at the end of Silver's section. Thanks to the game's hideously broken AIRoulette, it's entirely possible for the boss to not invoke its [[TacticalSuicideBoss tactical suicide]] enough times for you to deplete its health bar before it completely destroys the stage, sending you plummeting into the lava below and requiring you to restart the whole fight.
** The TrueFinalBoss of ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'', and some of the 3D games (including the aforementioned ''Sonic Adventure'',) is like this. You don't have an actual timer, but you start the fight as [[SuperMode Super Sonic]]. If you run out of rings, you turn back to normal, and in the boss fight, this causes you to die. This makes sense in S&K, as the fight takes place in space, but makes less sense in Sonic Adventure, where you could, hypothetically, run out of rings on a floating piece of road, but the game assumes you fell into the water and drowned regardless.[[note]]Probably because if you're not Super you can't do jack to the boss even if you ''did'' coincidentally land somewhere marginally less deadly.[[/note]]
** Another ''Sonic'' example: the Egg Golem from ''VideoGame/SonicAdventure2''..
** SonicRush and SonicRushAdventure's penultimate fights both end with this. After your FreeFallFight with Eggman/Nega in the former sinks below the clouds, he'll ram his mecha into the stage, destroying it if you don't hit him. After hitting him enough times in the latter, he'll instead fire [[LastDitchMove two extremely powerful lasers]] [[AdvancingWallOfDoom that close in on you.]] If you don't hit him when he gets close enough, you'll be [[OneHitKill obliterated]].
* [[VideoGame/PunchOut Mike Tyson]] destroys your platform in ''VideoGame/IWannaBeTheGuy''.
** So does TheGrimReaper in ''VideoGame/IWannaBeTheFangame''.
* In the 3rd ''VideoGame/ApeEscape'' game's true FinalBoss, Specter does this to you, passively. Why? To have you drop out of your super form.
* The final boss of ''VideoGame/SnowBros'' arcade is a very interesting example. There are two giant stone heads on each side of the screen, a small platform surrounded by flames in the middle and a descending ceiling full of spikes right above that. The heads continuously blow bubbles which can have enemies or power-ups inside, and these pop if they touch the spikes. The player has very little space to move, and the more the ceiling goes down, the faster the enemies can get him... of course, this also means that he can throw many more snowballed enemies against the heads, but he is forced to think and act much more frantically.
* The ''Franchise/StarWars'' game ''[[VideoGame/DarkForcesSaga Jedi Knight]]'' uses this in the final duel. Jerec must be defeated before the two statues at the edge of the valley reach the center, or he becomes too powerful.
* Reznor bosses of ''VideoGame/SuperMarioWorld'' are fought on a bridge which, after two hits, rapidly collapses from the middle. To survive, it's imperative to jump on the boss' rotating platform. Unless you're ''really'' fast, in which case the end trigger in which Mario doesn't fall anymore goes off before the end of the bridge (which you'll probably be on) can collapse.
** The secret boss, Big Boo, can only be defeated by tearing blocks out of the floor of the BossRoom, which creates a danger of falling through.
* Midway through the second fight against Dogadon in ''VideoGame/DonkeyKong64'', he throws a tissyfit and stamps repeatedly on the platform you're fighting on. In response, it starts to sink into the lava. If you're too slow to finish the battle, you're toast. Literally.
* The final boss in Shatterhand (NES) has a move that breaks away part of the floor, turning it into fire. it isn't an instant kill, but it does constant damage and you recoil from hits, thus making it part of this trope.
* Known as "soft enrage" in ''VideoGame/WorldOfWarcraft'', as opposed to "hard enrage", essentially a TimeLimitBoss.
** Professor Putricide in Icecrown Citadel in the 3rd phase of the fight. The room slowly fills with poisonous slime, reducing the amount of space there is to move around.
** The Lich King had something similar in his second phase, pools of corruption that would get larger the longer people stayed in them.
** And from the Cataclysm expansion: Commander Uthok in the heroic dungeon Throne of Tides creates permanent growing void zones on the floor that must be avoided. Groups with low damage will eventually find themselves with nowhere to stand.
** ''Mists of Pandaria'' brought us Jin'Rokh the Breaker, who would target one-quarter of the arena he stands in and fill it with electrified water. Players would then have to move to a clear section of the floor to continue the fight. (Especially annoying if he charges two opposite quarters rather than consecutive ones...)
* In ''Chains of Promathia'', the second expansion of ''VideoGame/FinalFantasyXI'', you have the fight against Diabolos. In addition to the standard time limit for any bossfight, you also have to contend with a floor that falls away, except for a number of panels which never do. The pit below isn't bottomless, it's simply filled with giant spiders.

* The TrueFinalBoss of ''[[VideoGame/GargoylesQuest Demon's Crest]]'' throws orbs that steadily turn parts of the walls and floor into damaging spikes. Your character can fly, but midair maneuverability is ''very'' limited.
** On the other hand, in order to encounter this boss, you must first acquire the ability to spit a type of fireball onto wall spikes that makes them temporarily safe to land on, so it's still merely inconvenient rather than inevitably lethal.

* The FinalBoss of ''VideoGame/PopfulMail'' also shot orbs that turned the floor into spikes. At least you do have an item that allows you to walk on spikes... but it lowered your jump height, leaving you vulnerable to his RocketPunch grab move.
* ''VideoGame/AlienSoldier'' had "Back Stringer". You fought this GiantSpider on the wings and body of its dinner, a [[http://www.bogleech.com/aliensoldier/as-spiderbattle.gif decapitated giant fly]]. Small destructible [[DemonicSpiders spiders]] would come up from the bottom of the screen and pull the fly down the big spider web (each additional one making it sink faster). If the fly platform disappears off the bottom of the screen, expect to [[GameOver die]]- you'll keep falling into a [[NonLethalBottomlessPits health-draining bottomless pit]] [[CycleOfHurting OVER AND OVER AGAIN!!!]]
* In her second-to-last form, the [[BigBad GoldenDiva]] of ''VideoGame/WarioLand 4'' starts smashing the floors of her arena. Miss too many chances to damage her, and you'll have nothing to stand on but spikes. Which are painful.
** Wario Land 1 has the big giant head that shoots rock boogers out of his nose and licks rocks. ... erm ... It's this trope.
* Bowser in ''VideoGame/SuperMarioBros3'', for both you and himself, although there are solid platforms too. Eventually he'll fall through the floor himself, or you can KillItWithFire (or hammers).
** In the final battle with him in ''VideoGame/SuperMario64'', after you score two hits on him, he smashes the platform, turning it into a smaller star-shaped one. Before this point, flinging him off the platform but missing the bombs around the edge will result in Bowser simply leaping back up, which can knock off one of the pieces that would otherwise fall after the two hits.
* In ''VideoGame/EccoTheDolphin: Defender of the Future'', the final boss is the alien queen's [[WombLevel heart]]. During the fight, blood rises from the bottom. if you don't defeat it quickly, Ecco will drown in the blood. [[JustifiedTrope Which makes sense]] because blood doesn't have air in it, and dolphins [[TruthInTelevision being mammals cannot breathe in any liquid whatsoever]].

* VideoGame/YoshisIsland: The [[BackgroundBoss final boss]] will start off by occasionally dropping boulders near where Yoshi stands, leaving sizable gaps. When he's about to die, he bum-rushes the arena to destroy all platforms and knock Baby Mario out of the saddle while Yoshi plummets. Pretty much screwed either way.
* In ''VideoGame/{{Purple}}'', the final boss will occasionally send down bolts of lightning that destroy the floor.
* Subverted in ''VideoGame/MassEffect2''. The FinalBoss periodically destroys some of the platforms which make up the battle area. However, it never destroys the platform you start out on, completely eradicating any sense of urgency.
* ''Franchise/MegaMan'' examples:
** In ''VideoGame/MegaMan4'', one of the attacks from Mothraya is to punch holes in the floor using its spike. Though it won't destroy the entire flooring, the added threat of BottomlessPits certainly will not make the battle any easier.
** ''VideoGame/MegaMan10'' apparently thought we missed this gimmick and combined it with perennial ThatOneBoss the Yellow Devil. This game's version, the Block Devil, forms itself out of wall and floor tiles (with nothing below them). It gives back the tiles after a while, only to relocate and repeat the process.
** In ''VideoGame/MegaManX2'', when Wheel Gator TurnsRed and starts executing his drill attack, whatever sections of the wall he hits are ground down into damaging spikes, which gradually prevents you from climbing the walls to evade his other attacks.
** In ''[[VideoGame/MegaManX4 X4]]'', there's the mid boss of Split Mushroom stage, Tentoroid. Thankfully it only takes a few charge shots to destroy, but if you're going for a no charge shot run like a certain [[LetsPlay/RoahmMythril dragon]] and his X-series equivalent Kevvl do, it's pretty tough to land enough shots before [[SpikesOfDoom spiky]] doom. [[http://www.youtube.com/watch?v=fioXsT65Zq0 Kevvl did pull it off, though]].

* While fighting The Beast in ''VideoGame/{{Apocalypse}}'', the pillars that serve as the boss arena collapse one by one as you damage him.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'': The fight against Ganondorf takes place in the top room of a tower, with Ganon in the middle and you standing on platforms along the edge. One of his attacks will know some of the platforms down, but the platforms in the corners are permanent. Downplayed, in that falling off simply sends you to the ground below from which you can climb back up.
* ''VideoGame/{{Bastion}}'' : Some of the larger ememies weild giant pickaxes that they attempt to hit you with. Sometimes they'll show up in the more unstable areas and take out chunks of the floor with each hit. They have low enough health that it's rare for them to take out an entire fighting space, but those holes they punch make it much harder for you to move around when you're being swarmed by smaller enemies. Most of whom can hover right over the holes no problem.
* During the Kracko battle in ''VideoGame/KirbyCanvasCurse'', Kracko will destroy the arena floor, the clouds.

* In the NES version of ''VideoGame/DoubleDragon II'', the rematch with Burnov in Mission 8 takes place on a floor over SpikesOfDoom that slowly disappears piece by piece.

* Just before the final boss battle, Don Ramiro of ''VideoGame/MalditaCastilla'' must destroy a giant cauldron that drops corrosive acid globs on the floor. Take too long and the acid will completely corrode the floor and make Don Ramiro fall in the bottomless pit below.
* In ''VideoGame/AzureStrikerGunvolt'', when you bring the final boss [[OneWingedAngel Nova's]] HP down to one-third, he uses a super attack that causes a meteor to come down directly above you, [[DescendingCeiling lowering your room to maneuver]]. Touch it by taking too long to win the fight or jumping into it, [[OneHitKill you die instantly]], and have to fight the boss' previous form all over again.

* The first boss of ''Amazing Princess Sarah'' destroys a floor every three attacks, and the last floor is over a BottomlessPit.

** Not exactly a proper example, but in ''VideoGame/SonicTheHedgehog4'', once the FinalBoss has 1 hp left, it will try a LastDitchMove to crush the floor and make Sonic fall into a BottomlessPit. You better get that last hit in before it's too late!

* The first boss of ''Amazing Princess Sarah'' destroys the floor you're on every three attacks, and the last floor is over a BottomlessPit.
