Utsujin the alien invader has still plans for world domination, and this time he brought with him purple goopy blobs called "Bumyon" that can envelop other life forms, so he plans to cover the planet with them to easily conquer it. Luckily, Hebe discovers that the Popoons (those round balloons with a face he can summon) instantly destroy Bumyons, so he will have to free his friends O-Chan, Sukezaemon and Jennifer from the alien goop and chase the invader around the land before his plan can be enacted.
Compared to the first Ufouria, this game is less of a Metroidvania and has more in common with rogue-lites, since it is set as a series of changing short platforming stages where the objective is to grab as many coins as possible. These coins will then be used to buy items in the vending machine conveniently set under Hebe's tree house, in order to unlock various abilities to explore the world and gain even more money.
Ufouria 2 provides examples of:
- Action Commands: Every now and then the other characters in your party will say that they have found something, and if you press the button when the input appears, they will unearth useful items like coins or hearts... or a poop.
- Ambiguously Human: Finally this game makes it clear that O-Chan is a blue-haired humanoid wearing a cat costume. Whether she's actually human, well...
- Art Shift: The Stinger has Hebe turned into his pixelated 2D self and brought at the beginning of the first Ufouria.
- Art-Shifted Sequel: This time the world is rendered as a 2.5-D place that looks like it's being made in felt, cardboard, clay, yarn and other common materials.
- Batman Can Breathe in Space: Invoked and discussed. When our heroes finally reach Utsujin on his mothership in outer space, they wonder how they are able to breathe and talk to each other.
- Bird-Poop Gag: Just like in the original Hebereke game (but not in Ufouria, where poop has been replaced by 16-ton weights), flying birds excrete the typical coily poop and you have to avoid it. Or to get hit by it 30 times to gain an achievement...
- Blob Monster:
- The result of several Bumyons fusing together. They're not alive though, more like immobile obstacles.
- The little jumping jellies from the first game are back, though now pink instead of green (because of climate change, the manual says). The big square stationary jellies are back too, not as an Unique Enemy this time but as objects you can jump on to gain more coins.
- Breaking the Fourth Wall: Several examples, like Jennifer saying that the game is not going to make things easier for them, or Hebe saying after buying the "Butt Book" that he in 30 years never learned to do a different butt stomp.
- Contrived Coincidence: Played for Laughs.
- Utsujin wants to use Bumyons to cover the world, and Hebe finds out by chance that Popoons act like anti-matter to them.
- The guy who restocks the vending machine apparently always puts into it items that are needed for the current situation, almost at any given moment.
- Denser and Wackier: There is definitely more humor than in the first Ufouria, especially from O-chan. Even the music that plays during the dialogue sequences is goofy.
- Double Unlock:
- For some items in the vending machine, it's not enough to have the correct amount of money, you also have to have the correct amount of Utsu Cans on your card. They are scattered around the stages and can be obtained in challenges.
- Beating your friends in combat is not enough to make them join your party, you also have to buy the respective item from the vending machine as to make them happy. A microphone for O-Chan, some rare tea for Sukezaemon and an "epic antacid" for Jennifer.
- 11th-Hour Superpower:
- Before the final confrontation, Utsujin slathers himself with "Super Bumyon" that makes him immune to Popoons. Though you can still jump on his head with no problems.
- After Utsujin has been defeated, there's still the Bumyon problem. Our heroes randomly discover that by summoning all of their Popoons at the same time, they can generate a wormhole that instantly sucks up all the blobs. However Hebe too gets sucked into it...
- Forest of Perpetual Autumn: A new biome introduced in this game and the place where Hebe finds Sukezaemon. It has a very Japanese appearance, complete with stone shrines.
- Hailfire Peaks: Downplayed example. The entrance to Chilly Caves is an ice sheet that is located right next to a lava pool and a volcanic area.
- Hand Wave: There are optional re-matches of boss fights. Since three of them involved fighting the other main characters (O-chan, Sukezaemon and Jennifer), one asks how that works if they have to fight each other again. It's theorized that maybe they're just fighting holograms of each other.
- Heavy Sleeper: Jennifer was sleeping in his room and didn't even notice Utsujin's arrival and all the blobs around. He also has a tendency to nod off during the adventure. It's probably due to his bad digestion.
- Inexplicable Treasure Chests: This time they only hold money, not items. Japanese-style ones appear every time you defeat a boss.
- Informed Species: Turns out that a few enemy types are actually Earth animals according to the bestiary. Mickys, those guys with Mickey Mouse ears, are actually koalas. Other beings (only seen frozen in ice at the end of one ice cave stage) are apparently wallabies.
- Lava Is Boiling Kool-Aid: Averted, this time lava is the only obstacle in the game that can insta-kill you.
- Monster Clown: They are back, but they aren't enemies this time, after buying certain items they will introduce you to optional challenges that if completed lead to more coins and Utsu Cans. The bestiary also implies they're from another dimension, for whatever reason.
- Monster Compendium: One item that can be unlocked late game is a guide that gives some funny tidbits about every enemy in the game.
- Mythology Gag: An easter egg when sometimes, on the way back home courtesy of Bobodori the bird, Hebe and O-Chan will be randomly replaced by Bop-Louie and Freeon-Leon from the Western Ufouria localization during the brief cutscene.
- Opening Shout-Out: A very wacky (and thus appropriate) example. The opening cutscene shows Utsujin coming to Earth on his UFO and avoiding every kind of random floating debris (a radish, a bicycle, a phone booth...) on the way. When our heroes build a rocket to go to space and confront Utsujin, they will have to avoid those exact items on the road to outer space while bouncing on the clouds.
- Percussive Maintenance: One of the buyable items is an old-school CRT television that supposedly raises the game's difficulty, as a reference to old games being played on those kinds of TV. When Hebe buys it, it doesn't seem to work, and starts to show some cartoons only after O-Chan punches it.
- Piñata Enemy: Sometimes a golden Kerasu (bird) will appear and if you defeat it you will gain a whopping 300 coins.
- Sequel Hook: Two possible ones. Though the ending implies this is a prequel to the original game, so in a sense the sequel already happened
- Utsujin mentions that he has failed Master Unyohn when defeated. Unyohn is a Space Pirate and the Big Bad of the Ufouria series.
- Hebe falls in a wormhole and gets transported to the world of the 1991 Ufouria.
- Take That!: One of the obstacles hurting you in the last leg of the game, the journey to outer space, and that can also be found in an optional underwater area, is the board used to announce the beginning of the Reiwa Era
◊. As if to say that it has been a terrible period for Japan and the world at large. - Toilet Humour:
- There's an achievement for getting hit 30 times by bird poop.
- In one cutscene Hebe uses the water from his toilet to wash his face, since he doesn't have a sink, bathtub or anything else.
- The Unfought: The knight kitten boss returns with his shower of lances, but just as an immobile obstacle in some advanced stages. The characters mention that they can't do anything against his armor, and there's no apparent way to actually fight him.
- Years Too Early: This time the references to Japan are much more common, instead of having as a set a fantasy world with very few links to reality. O-Chan in particular uses a few Japanese Stock Phrases in her dialogues, but adding comically exaggerated descriptors, fitting for her theatrical, bombastic personality."How dare you! You're 12.86 trillion years too early to speak to me so!"
