Pyukumuku

Sun: It lives in shallow seas, such as areas near a beach. It can eject its internal organs, which it uses to engulf its prey or battle enemies.

Moon: These Pokémon line the beaches. The sticky mucous that covers their bodies can be used to soothe sunburned skin. How convenient!

Ultra Sun: The tradition known as Pyukumuku chucking started from the custom of throwing Pyukumuku back into the sea after they wash onshore.

Ultra Moon: Its entire body is covered in its own slime. If you accidentally step on one, you’ll slip, and it will get mad and smack you!

Sword: It lives in warm, shallow waters. If it encounters a foe, it will spit out its internal organs as a means to punch them.

Shield: It’s covered in a slime that keeps its skin moist, allowing it to stay on land for days without drying up.
