Jellopus

Jellopus are jellyfish enemies from Wario Land: Shake It!. They only appear in underwater levels with the Subwarine. They appear in cyan, yellow, and purple variations. They move in a wavy pattern.

Blue Jellopi just swim around in a carefree manner and pose no threat. Yellow Jellopi swim in a wavy pattern and can be sort of a nuisance. Purple Jellopi, on the other hand, discharge electricity. When Wario is close enough, the Jellopus will discharge four balls of electrical energy which will damage Wario if he is hit by one.

Trivia

 * Its name comes from Jellyfish and Octopus, being that it has a resemblance to both creatures.
