''Tails Adventure'', also known as ''Tails Adventures'', is a {{Metroidvania}} game in the ''Franchise/SonicTheHedgehog'' franchise. It was released for the Creator/{{Sega}} UsefulNotes/GameGear in 1995. It is one of three spinoff games that Tails recieved, the other two being ''[[VideoGame/TailsSkyPatrol Tails' Skypatrol]]'', which was also on the Game Gear, and ''Tails and the Music Maker'', which was for the Sega {{Edutainment}} System, the [[UsefulNotes/OtherSegaSystems Sega Pico]].

While taking a nap outside his house, Tails is woken by an explosion. The Battle Kukku Army has invaded the island in order to find the Chaos Emeralds, and it's up to Tails to stop them.

This title is different from other games in the ''Sonic'' series in that the emphasis is on visiting and revisiting different stages in a similar vein to ''[[VideoGame/ClashAtDemonhead Clash at Demonhead]]''. Also, unlike previous titles, Tails actually reaps benefits from collecting ''just one'' Chaos Emerald (an increase in HP and Flight stamina).

The Japanese manual says this game [[{{Prequel}} takes place on Cocoa Island before Tails first met Sonic]], while the Western manual says it takes place after Sonic and Tails' last adventure and Tails is on vacation on Tails Island.

It has a comic book tie-in in ''[[ComicBook/ArchieComicsSonicTheHedgehog Sonic Universe]]'', though it took a few liberties with the plot (such as it is). The Battle Kukku Army, referred to as the Battle Bird Armada, has since taken on a role as one of the major villain groups in Archie's ''Sonic'' series.
!! ''Tails Adventure'' features the following tropes:
* HundredPercentCompletion: You need to collect all Items and Emeralds.
* AdaptationalWimp: To fit in with the slower paced gameplay, Tails' default flight ability and speed are extremely nerfed compared to how he plays in the standard ''Sonic'' games. While the Chaos Emeralds do beef up his flight considerably, the Sonic item doesn't make him move as fast. This is averted in the Japanese version, in which the story takes place before Tails met Sonic, [[JustifiedTrope so it makes sense that he's not very fast nor knows the Spin Dash yet]].
* ADayInTheLimelight: Tails is the main protagonist of this game.
* AwesomeButImpractical: The Knuckles item. The concept of Tails punching his foes is awesome...until you find out how terribly short-ranged it is.
* BigBad: The Grand Battle Kukku XV, the leader of the armada.
* BunglingInventor: [[spoiler:Tails is shown in this light in the closing credits.]]
* BusmansHoliday: In the Western manual's story, this game takes place during Tails' vacation.
* TheCameo: While Sonic and Knuckles do not appear in person, two items, the Sonic Item and the Knuckles Item, have their faces adorned on them. Fang also has his own item as well.
* ComicBookAdaptation: Issues #16-18 of Archie's ''Sonic Universe'' comic.
* ConvectionSchmonvection: Used in the Poloy Forest level. The entire forest has been set ablaze, but Tails strolls through without breaking a sweat or running into a lick of the flames. The flamethrower robot at the end of the level is another story.
* CoolBoat: The Sea Fox. It also functions as a CoolAirship.
* DropTheHammer: The (Pikkon) Hammer item.
* EndGameResultsScreen: Post-credits, the game shows you your item collection ratio.
* FinalBoss: The BigBad and leader of the Kukku army is fought on his ship as the second opponent in a double-boss fight immediately after his son Speedy is defeated.
* GadgeteerGenius: Tails is able to convert the Remote Robot [[TransformingMecha into the Sea Fox]].
* GaidenGame: A spinoff that features Tails as the main protagonist.
* GoodLuckCharm: The Fang item functions like this. Just bringing it with you will increase the chances of enemies dropping rings, no activation necessary.
* HitboxDissonance: Napalm Bombs, hornets, and hornet hives behave strangely together. Napalm Bombs will damage both of these things (including the big one that appears from destroying the hive) as long as they occupy the same vertical space. Even if it the sprite passes well under them, it'll damage them for no apparent reason.
* InfiniteSupplies: Every one of Tails' projectile attacks have an infinite quantity, as does the Sea Fox.
* InvincibleMinorMinion: Oddly enough, ''you'' get one in the form of the Robot. Spikes, enemies, lava...nothing can kill it.
* JokeItem: The Radio. All what it does is [[SoundTest change the soundtract]].
* KidHero: Tails.
* {{Leitmotif}}: The title screen music is woven into a couple of other tunes in the game, serving as a somewhat downplayed leitmotif for Tails.
* {{Metroidvania}}: While the game's levels are not all conjoined with one another, collecting upgrades and revising previous areas with said upgrades will open up new paths and even more upgrades.
* MiniMecha: The bosses of Poloy Forest, Volcanic Tunnel and Cavern Island are these.
* NightVisionGoggles: An item you can get that is required for Polly Mountain 2.
* OddballInTheSeries: A ''Sonic'' game that not only isn't centered around speed, but is a slow paced Metroidvania sandwiched in instead of a linear arcade like platformer. To say the least, it's a drastic change of pace for the series.
* OverlordJr: Speedy is said to be the son of the leader of the Kukku army. Appropriately, he's the last boss and the first opponent in a SequentialBoss fight before you meet his father.
* PermanentlyMissableContent: When you complete Coco Island, it will be replaced by the Battle Fortress, meaning that if you didn't collect the two items there (Teleport Device and Yellow Chaos Emerald), they'll be lost forever.
* {{Prequel}}: According to the Japanese manual, this game takes place before Tails met Sonic.
* TheRival: Speedy, who Tails has to outmaneuver early in the game. Speedy returns as the semi-final boss of the game and the first opponent in a double-boss fight to end the game.
* RobotBuddy: The Remote Robot.
* RobotMe: The Remote Robot. Its name is even "Mecha Tails" when playing on a Japanese Game Gear.
* SelfImposedChallenge: Beating the game with only one Chaos Emerald collected.[[note]]The one the game forces on you at Polly Mountain 1.[[/note]] This leaves you with only 20 HP and a 6-second flight timer[[note]]this can be circumvented by immediately pressing the jump button to re-fly as you start to fall[[/note]] to tackle the rather relentless latter half of the game. A total low-item completion run (using only the mandatory equipment) is also possible, to a point - [[MacrossMissileMassacre the underwater cannon gauntlet]] that leads to Kukku Island is so punishing that getting through without the [[NighInvulnerable Mirror Armor]] is almost impossible.
* SoundTest: The Radio item acts as a portable Sound Test that you can use during gameplay.
* SpellMyNameWithAnS: In the ''[[VideoGame/SonicAdventure Sonic Adventure DX: Director's Cut]]'' summary, Cocoa Island and Great Battle Kukku were properly translated, but they were respectively mistranslated as "Kokko Island" and "Great Badoru Kukku" in the ''Sonic Gems Collection'' manual. Also, Kukku Island is similarly known as Coco Island when the game is set to English - which may mean that it was supposed to be "Cuckoo".
* StuffBlowingUp: Tails uses bombs as his main weapons.
* ThisIsADrill: The Sea Fox's drill bit.
* TransformingMecha: In three areas, the Remote Robot can transform into the Sea Fox.
* TheUnfought: In the Archie comic adaptation, Tails doesn't even ''meet'' [[BigBad Grand Battle Kukku XV]].
* VillainOfTheWeek: The Battle Kukku Army, in one of the very rare occasions where Dr. Robotnik is not the villain of a ''Sonic'' game and is completely absent from one.
