[[caption-width-right:350:I am Blobert, eater of worlds.]]

Released by Creator/AbsoluteEntertainment in 1989 for the UsefulNotes/NintendoEntertainmentSystem, ''A Boy and His Blob: Trouble on Blobolonia'' (yep, that really is the game's subtitle), features the adventures of our eponymous hero (the Boy) and his friend Blob (full name Blobert) as they race to Blob's home world to defeat the evil emperor.

The main draw of this platforming game (which was created by David Crane of ''VideoGame/{{Pitfall}}'' fame) is that Blob has the uncanny ability to change into different shapes/objects depending on what type of jellybean the boy feeds him. From licorice to ketchup, each flavor turns Blob into a different shape, allowing the boy to overcome obstacles and complete each level.

Numerous remakes were rumored since its release, but for twenty years the series consisted of only the original and a 1990 sequel for the UsefulNotes/GameBoy, ''The Rescue of Princess Blobette''.

It was finally resurrected on the UsefulNotes/{{Wii}} in 2009 by Creator/WayForwardTechnologies, makers of ''VideoGame/{{Shantae}}'' and a bunch of licensed stuff, as a level-based puzzle platformer. The two main characters among with others were redesigned too. A high-definition update of this game was released for [[UsefulNotes/MicrosoftWindows Windows]] (via UsefulNotes/{{Steam}} and Website/GOGDotCom), UsefulNotes/PlayStation4, UsefulNotes/PlayStationVita, and UsefulNotes/XboxOne on January 19, 2016.
%% Content free examples have been commented, uncomment only after adding an explanation.
!!Both games provide examples of:
* AdiposeRex: The Emperor of Bloblonia.
* AlliterativeName: Those jellybean names that ''aren't'' pun-tastic tend to be these. Both games have the Licorice Ladder and Tangerine Trampoline.
** The original contains the Root Beer Rocket.
** The Wii game replaces Root Beer with Cinnamon for the rocket, but gives us in return: The Berry Balloon, Bubble Gum Bouncer, Pear Parachute, Cream Cannon, Strawberry Shield (replacing Strawberry = Bridge in the original), and Cotton Candy Copy.
* BatmanCanBreatheInSpace: The inevitible trip to Blobolonia. [[spoiler: And back again in the Wii version.]]
* BlobMonster: But the Blob isn't so much a monster in this game.
** Some of the sequel's enemies fit into a BlobMonster category as well.
* ABoyAndHisX: Just look at the title.
* CollisionDamage: It applies to some of the enemies too if they collide with different enemies.
%%* EdgeGravity
* EternalEngine: In NES version, the sweets factory. In Wii version, the earlier levels of world 4.
* FatBastard: The Emperor of Bloblonia. In the original game, this was part of the alleged {{Aesop}}, because the game had a whole "candy is bad for you" theme and the Emperor was just a ''sapient blob of fat.'' In the Wii version, there's no such moral anymore, so he's just your standard big fat jerk.
* InexplicableTreasureChests: Who leaves those things scattered around the forest, city and Bloblonia anyway?
* KidHero: The titular Boy, obviously.
%%* MalevolentArchitecture
* NoNameGiven: You're just a boy after all.
* NotTheFallThatKillsYou: Fall more than two screens without landing on something soft or bouncy, and you'll die.
** This also applies in the Wii version. If the boy falls far enough to start tumbling (about one screen in height), he's doomed. Be very careful about where you Trampoline to....
* OneHitPointWonder: There is no health bar. Anything that can hurt the boy, can kill him instantly.
* ParentalAbandonment: In the Wii game, the Boy is especifically said to be around 6 years old. Where on Earth are his ''parents?'' The original looks like a teenager, so he's probably OK on his own, but still..
* PortableHole: When fed a fruit punch flavored jelly bean, the blob turns into the [[IncrediblyLamePun Punch Hole]], which fits this trope.
* RequisiteRoyalRegalia: All kings and emperors in the series seem to wear crowns.
* RidiculouslyCuteCritter: Admit it: You want a Blob of your very own, don't you?
* RocketRide: With your blob as a rocket.
* ShapedLikeItself: Coconut Jellybean = Turn Blob into a coconut. Natch.
* SpikesOfDoom: Ooooh yeah. All over the place...
* StalactiteSpite: It's one of the few things that can kill the Boy when he's in the Cola Bubble.
* {{Pun}}: A number of the jellybean's abilities are linked to their flavors. Both versions have Punch = Hole, Apple = Jack, and the original has Lime = Key. (* [[CollectiveGroan groan]]* )
* SuperDrowningSkills: The Boy and the enemies. Of course, as mentioned above, he can still breathe in space.
* SuperNotDrowningSkills: While the boy can't swim, the Blob is unable to sink if he's not a bubble or an anvil.

!!The 1989 game and UsefulNotes/GameBoy sequel provide examples of:
* ActionBomb: Cherry bombs explode when they touch the ground, and are fatal even if they detonate off-screen.
* AmericanKirbyIsHardcore: When the NES game was released in Japan, the Boy and the title screen were changed to look "cuter". HilariousInHindsight when the Wii remake made the boy "cuter" as well.
* AwesomeButImpractical: The Vitablaster. It's a gun (made by feeding Blob an Orange jellybean) that can be used to kill enemies on Blobonia by shooting them with [[AbnormalAmmo vitamins]]. However, doing so puts you at risk of dying and it's far more efficient to just roll the coconut a huge distance into the screen to make them go away.
* BrokenAesop: The original game seems to be saying sweets are bad (marshmallows and chocolate kisses can kill you, and vitamins are used to destroy them) yet jellybeans are the Blob's source of power and peppermints are traded in for extra lives. Cherries (or more accurately, cherry bombs) are among the things that kill you.
* ChekhovsBoomerang: The Apple Jack is only used to open the manhole cover [[spoiler:and defeat the final boss]].
* DummiedOut: Tricking Blob into eating a ketchup jellybean will turn him into a brick wall. The brick wall is essentially just a stepping stone.
* TheGhost: The Evil Alchemist responsible for capturing the princess in the Gameboy title, who never shows up in the game itself.
* GravityIsAHarshMistress: Sometimes, when screeching to a halt at the edge, the Boy will suddenly stand in midair. In true cartoon physics fashion, he will gradually look down, realize his situation, and fall, usually to his death.
* LeapOfFaith: Or more accurately, fall of faith. In the subway, placing the hole at the wrong position may cause you to fall multiple screens.
* NintendoHard: Only a handful of lives and no continues.
* ParasolParachute: Vanilla = Umbrella.
* SaveThePrincess: In the ''Rescue of Princess Blobette''.
* ScriptBreaking: Normally, getting past a screen on Blobolonia clears it, allowing you to pass without further interference. Throwing the bean off the left of the left-hand screen will trick the game to think that all such screens are cleared.
* TreasureIsBiggerInFiction: Large blue gems.
* TrialAndErrorGameplay: Some challenges require you to prepare for them before you enter the same screen.
* UnderTheSea: The caves in your world have water in them, and you won't be able to survive unless you feed Blobert a jellybean that turns him into a bubble.
* UnwinnableByDesign: Wasting your beans is technically UnwinnableByInsanity as you have more than enough to naviagate known areas. However, there are only two lime beans - you only need one, but if you experimented to see that it creates a key, and accidentally throw the second on the ground, you can't reach the emperor.
* AWinnerIsYou: The NES release is a particular offender in this department.
* YouHaveToBurnTheWeb: There's only one web, but plenty of jelly beans to burn it away.

!!The 2009 game provides examples of:
* HundredPercentCompletion: Getting all 3 treasure chests in a level unlocks a challenge level. Beating challenge levels unlock things like concept art and some other stuff.
* AllAnimalsAreDogs: The developers said that the personality of the Blob is largely based on dogs.
* AnvilOnHead: The Banana Anvil is very effective when it comes to enemies.
* ArtificialStupidity: At least the game is kind enough to note it -- When Blob cannot reach the player or seems to be getting stuck, he turns pink (as he turns gray near the enemies).
%%* AwardBaitSong: Yes, [[http://www.youtube.com/watch?v=P3dXDRqWTKI this]].
%%How is this an award bait song?
* BittersweetEnding: [[spoiler: The evil emperor is defeated, but Blob has to return to his planet. The credits play a song called "Everything to Me" about how the blob is the greatest thing ever to happen to the boy, accompanied by a montage of pictures of them playing together with nobody else in sight, culminating in an end screen of him staring up at the moon.]]
* BlackoutBasement:
** Level 2-6. Blob helpfully eats a firefly to help you light the way, but if you don't have Blob cling close to you, you'll have ''no'' idea where you're going.
** The "grand prize" for completing the T-rex set of Challenge Levels in World 2 is an orb that you can use to turn the lights off and play ''any'' level in this manner if you want.
* BottomlessPits: A quick way to test them is to throw a jellybean down and watch the Blob take the plunge for you; if it's bottomless, he'll transform into balloon form and float right back.
* BubblegloopSwamp: Second half of the first world.
* ButNowIMustGo: [[spoiler: The blob returns to his home planet at the end, leaving the boy alone after an emotional farewell.]]
* CameFromTheSky: How the Blob got to earth.
* TheCameo: There's a VideoGame/{{Shantae}} doll on the bookshelf in the World 2 Hub.
%% The following sounds like an aversion, of dubious notability. If the devs originally intended it to be more casual, or marketed it as being so, or something, I think that might probably better go on the trivia page? Something seems wrong about this example, but there might be something worthwhile here, so I'm going to just comment it out. Someone please fix this example or refactor the information to go somewhere else.
%%* CasualVideoGame: The developers wanted it to be "accessible", so divided it into two parts: Ordinary story levels, and unlockable "Challenge" levels for the {{Challenge Gamer}}s. What they ''neglected'' to mention is that the later levels of the story mode are ''every bit as NintendoHard.'' Ouch.
* CombatTentacles: The second boss, the Beast, has an entire back full of writhing, deadly tentacles.
* ConceptArtGallery: At all the hubs after completing challenge stages. There are a few videos mixed in too.
* ConspicuousCG: The opening movie is full of it.
* ContinuityNod: The Boy is significantly younger than the original Boy... but he wears the same clothes, right down to the colors.
* CoolChair: The main villain sits on one with heads and all.
* CraniumRide: You can ride on certain enemies if you drop an anvil on their heads, which allows you to safely ride them.
%%* CreditsMedley
* CreepyTwins: One of the enemy types is a pair of twin blobs. Drop an anvil on one of them, and the other one will counter by transforming into a Giant blob.
* CutscenePowerToTheMax: The opening movie depicts the blob eating a bean and transforming. All in midair. (The blob actually ''can'' catch jellybeans mid-air, but he usually waits for them to land before trying to chase them down.)
* DarkIsEvil: All enemy blobs are black (though the blob emperor himself is grey).
* DirectionallySolidPlatforms: You need a hole to get back down from these.
* DisneyDeath: In the second-to-last level, right before the EleventhHourSuperpower kicks in, [[spoiler: one of the Emperor's blob-tentacles appears to squeeze the Blob to little bits. However, a few SwissArmyTears--and the fact that he's a ''blob''--help the Blob get back together in no time]].
* DittoFighter: A certain jellybean will make Blob turn into Boy's shape and replicates his movements. One of the enemies can also do so.
* DummiedOut:
** The enemy concept art shows a Spider Blob enemy. It is seen standing among the other enemies in the finalized art. You never encounter it, however.
** There's a test movie in the game's data. Its the intro to the ''WesternAnimation/SamAndMaxFreelancePolice'' cartoon, oddly.
* EleventhHourSuperPower: [[spoiler: InstantAwesomeJustAddMecha]] during the penultimate level.
* EnergyBall: Final boss can fire these.
* EvilLaugh: When you meet the evil emperor.
* EvilOverlooker: On its box art.
* FamilyUnfriendlyDeath:
** [[spoiler: The emperor gets ''punched repeatedly in the skull by a giant robot,'' while ''bleeding black goo,'' and then, when he finally dies, he turns into a ''roiling mass of blackness as his face '''TEARS INTO TINY PIECES''''' and he dissolves.]]
** Killing the frog mooks by having the blob change from his coconut form to his basic form ''while inside it''.
** What happens to the boy if you fail. Picture this scene: A 6-year old boy with no special powers falls 80 feet into a bed of spikes, slumps over, and stops moving. He's obviously dead. Fade to black, [[DeathIsASlapOnTheWrist reload the checkpoint.]]
* {{Foreshadowing}}: The world 2 boss can be seen wandering around the background as you traverse his level.
* FourFingeredHands: A rigorously enforced part of the Boy's design, to help make him as cuddly as possible.
* GenreThrowback: Art style and the trailer of the game in inspired by 80-s cartoons and films.
* GhibliHills: The Boy makes his ho-- er, tree fort in some truly beautiful forest land. It's right next to BubblegloopSwamp, though. (But it's still beautiful.)
* GlowingEyesOfDoom: The enemies have them.
* GustyGlade: Numerous, with Challenge 2-5 being a standout.
* GuideDangIt: In most cases, inverted. The hint signs are everywhere. They're left there as a remnants of the development and playtesting stage of the game development.
* HeliCritter: One of the pieces of native wildlife in Blobolonia.
* HelpfulMook: Although they can still kill you, you can drop Anvil Blob on large enemy Blobs (and the small cannonball ones) to go on a CraniumRide of sorts. The large ones will also happily toss your Cola Bubble around to help cover large distances. Enemy blobs can also weigh down pressure plates (especially the Enemy Clone blobs) and set off the exploding blobs that hover in midair.
* HubLevel: One for each of the 4 main worlds.
* HumanCannonball: When your blob has a cannon form, that's what the boy can do while being able to stay invulnerable to some of the threats.
* InfiniteSupplies: Boy carries an infinite amount of jellybeans, to prevent the player from getting stuck in the middle of a level.
* InterfaceSpoiler: [[spoiler: Directly ''inverted.'' All of the levels are 10 stages long, right? World 1 had 10, World 2 had 10, World 3 had 10, World 4 has... wait, why are you facing the FinalBoss? It's only the end of Level 4-8! [[WhereItAllBegan Why are we back in World 1?]][[YourPrincessIsInAnotherCastle Wait, did someone tape ''two more levels'' to the end of the map?]] OhCrap...]]
* JustEatHim: If you get too close to the giant fat blobs they will swallow you. Also the frog enemies will eat Coconut Blob... [[FamilyUnfriendlyDeath only for him to emerge from their insides when you call him]].
* LevelAte: Bloblonia comes pretty close. Some parts of it do look organic, but there's a lot of towering gelatin-mold spires and jellybeans everywhere.
* LoadsAndLoadsOfLoading: In levels with lots of doors.
* LogoJoke
* LongSongShortScene: Done intentionally! There are four ''very'' hidden songs found only in the SoundTest (ItMakesSenseInContext). Musically, they don't fit the style of the rest of the game. However, they'll sound... ''familiar'' to those who've played the original game...
* LuckilyMyShieldWillProtectMe: One of the Blob's powers in World 4 is a shield that can block enemy blobs.
* MoodWhiplash:
** The [[GhibliHills absolutely beautiful]] opening levels are as lovely and as soothing as can be, full of fireflies and gently swaying trees... until you hit Level 1-10. "This music sounds... different. Everything's so red! I've got a bad feeling about this... HOLY CRAP OH MY GOD WHAT THE ''HELL'' IS THAT THING!?"
** The poor Blob [[spoiler: getting a DisneyDeath]], followed immediately by the EleventhHourSuperpower kicking in.
* NewPowersAsThePlotDemands: Blob seems to just gain new powers and jellybeans without reason from level to level.
* NoGearLevel:
** Level 4-1 requires you to traverse the entire level without Blob at your side. Blob? BLOB!?
** Beginning of the penultimate level has this thing happen too.
* NostalgiaLevel: Level 11.
* NoticeThis: "Follow the fireflies" is a good maxim to follow if you want to find all the treasures.
* OneHitKill: All bosses take three hits to defeat, except the boss at the end of the fourth and apparently final world.
* OneWingedAngel [[spoiler: The Emperor's final form even has copious mouth-tentacles to put you in mind of [[Franchise/CthulhuMythos Cthulhu]]. And [[WesternAnimation/{{Futurama}} Zoidberg]].]]
* PlayingTennisWithTheBoss
* PressurePlate: Quite a lot of them, especially in the last world, as well as several of the challenge stages.
* PullingThemselvesTogether: With the help of SwissArmyTears.
* PuzzleBoss: All of the bosses. Makes sense, since it's pretty much a puzzle ''game.''
* RedSkyTakeWarning: Before and during the first boss battle and during the final boss battle.
* RespawningEnemies: But only those critical for completing a nearby puzzle.
* RingInventory: The menu for selecting the jelly beans.
* SceneryPorn: Some ''absolutely gorgeous'' hand-drawn artwork makes up the backgrounds.
* SceneryGorn: [[spoiler: The second half of World 3, which features a decayed, dying version of the Dr. Suess-like scenery in the first half of world 3.]]
* SelfImposedChallenge: Playing all levels with the orb that turns off the lights.
* ShapeshifterBaggage: Officially, the Blob maintains the same volume in all transformations; larger forms (like the Cannon and Bubble transformations) are merely light and hollow. However, only the Anvil and Clone transformations are heavy enough to weigh down pressure plates.
* SilenceIsGolden: The game has no dialogue... at all. (Well, the Boy yells "Blob!" and "Let's go!") And ''barely'' any on-screen text. Even the "hint signs" just show pictures! It works, though.
* SoundTest: One of the unlockable bonuses in the World 3 Hub level: A level with a variety of friendly Blobs, who play music when you feed them jellybeans.
* SpoilerOpening: The opening movie displays many of Blob's powers, as well as three of the four major bosses.
* StockVideoGameSettings: All four worlds. World 1 is GreenHillZone and BubblegloopSwamp. World 2 is DeathMountain and proper {{Underground Level}}s. World 3 is SceneryPorn and SceneryGorn variants of {{Wackyland}}. World 4 is EternalEngine and EvilTowerOfOminousness. [[spoiler: The final two levels bring back Green Hill Zone.]]
* SugarBowl: The game specifically set out to evoke a heartwarming, Disney[=/=]Studio Ghibli-esque feel.
* SugarApocalypse: [[spoiler: When you reach the second half of world 3, you realize that a wide radius around the blob emperor's castle has become a decayed wasteland version of the [[SugarBowl vibrant environments]] you had just been through in the first half.]]
* SwissArmyTears: Seems to work. Makes you wonder if they wouldn't have worked.
* TemporaryPlatform:
** Small floating platforms will shake and fall when you step on them, but they respawn, too.
** The final challenge level (1-12) has one room where a basic enemy Blob moves back and forth across a PressurePlate, toggling between two sets of platforms that are form your only way of crossing a bed of spikes (and a hill).
* ThemeMusicPowerUp: Once the EleventhHourSuperpower finally makes its appearance.
* ThereWasADoor: Your first appearance in the World 3 hub involves crashing through the roof. [[spoiler:Averted when going from World 4 back to World 1, since the boy and the blob just fly in through the open window instead.]]
* TreehouseOfFun: The World 1 Hub.
* TriumphantReprise: After the blob is [[spoiler: brought back to life and turned into a mech]].
* [[spoiler: TrueFinalBoss]]: It actually manages to be a surprise for once, due to a variant on InterfaceSpoiler.
* ATwinkleInTheSky: During the ending.
* UnexpectedGenreChange:
** Level 14/2-4. It's the first level you can use the Cola Bubble jellybean in... and it plays more like something out of ''Franchise/SonicTheHedgehog'' than the other levels.
** The World 2's Challenge level #10, which involves flying the Root Beer Rocket through a massive labyrinth full of DeadlyWalls.
* VideoGameCaringPotential:
** There's a "Hug" button; yes, you read that right.
** The fourth world also has a number of caged blobs in the Emperor's citadel. Feeding them a Berry Balloon bean will free them, but you get nothing for doing so beyond warm fuzzy feelings.
* VideoGameCrueltyPotential: The game has a "Scold" button. Not that it does much beyond making the Blob stay in place until you call him.
* {{Wackyland}}: Third part of the game.
* WeirdMoon: Always full and large.
* WhereItAllBegan: The game's final two levels are not in World 4. No, they're all the way back in ''World 1.''
* WorldShapes: Bloblonia is very... bean-shaped.
* YourPrincessIsInAnotherCastle: When the FinalBoss comes at the end of ''level 8'' of what's normally a 10-level world and all it takes to defeat him is a OneHitKill before he slinks away, you know something more has to happen...
