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.
These Pokémon line the beaches. The sticky mucous that covers their bodies can be used to soothe sunburned skin. How convenient!
The tradition known as Pyukumuku chucking started from the custom of throwing Pyukumuku back into the sea after they wash onshore.
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!
