The titular egg-shaped character who's the mascot for Kansai TV
is on a quest to collect detachable lips around Japan after a herd of cows had theirs stolen. To get around, he must use his bill-like lips to grapple on surfaces and smack foes.
This game smooches the following tropes:
- Action Bomb: Black hachiemon enemies detonate when the hero gets close to them.
- Attack Its Weak Point: Certain bosses have a weak spot and will take double damage and flash red when hit there. However, their Mercy Invincibility will last longer in this case.
- Battle Boomerang: Hachiemon's lips can be thrown as a boomerang to damage enemies and reveal hidden items.
- Credits Gag: In the staff roll, hiragana characters that resemble a pair of lips are highlighted.
- Difficulty Levels: Harder difficulties raise the amount of lips required to clear each level and spawns more enemies — moving spike balls in particular.
- G-Rated Sex: When Hachiemon kisses certain girls, they pop out an infant that's worth an 1-Up.
- Gag Lips: The Game.
- Idle Animation: If the hero is left standing on the spot for a couple of seconds, he turns around and farts. Characters on the screen will facefault when this happens, but it has no practical function and will leave Hachiemon vulnerable to various hazards.
- Kiss of Death: Hachiemon can kiss enemies to make them embarrassed. In this state they can be used as platforms and grapple targets.
- Macro Zone: One powerup makes Hachiemon tiny so he can go through single-block sized passages.
- The Maze: One stage is a door maze and two latter ones are a maze of tunnels.
- Pistol-Whipping: The gunslinger boss of stage 21 does this after being knocked off his horse.
- Planet of Hats: In the game's setting, every creature and every object has large red lips attached to them. Even the island the final stage takes place in is shaped like one.
- Platform Hell: Some of the latter stages demand fancy grappling over bottomless pits.
- Rolling Attack: Hachiemon can spin dash, but only for four revolutions at a time or he'll get dizzy.
- Scary Stinging Swarm: Stage 8 ends with a boss battle against a swarm of bees.
- Segmented Serpent:
- The stage 17 boss is a conga line of hachiemon people.
- The stage 22 boss is a hydra that divides themselves into serpents with spiky tails.
- Slippy-Slidey Ice World: Stages 5 and 6 are ice-themed.
- Video Game Flight: The powerup in stages 16 and 17 allows Hachiemon to fly.
- Vocal Dissonance: Hachiemon is a cute clumsy guy who sounds like a baritone.
