Gunion

Gunions are octopus-like enemies in Super Mario Land, found in the Muda Kingdom. Gunions have a simple attack pattern and subdue the Marine Pop whenever it comes into range. If shot three times, it will split into two balls, each of which will home into Mario. Defeating a Gunion nets Mario an extra 400 points. Gunions are only found in World 2-3, the Marine Pop's level.

A green Gunion is among the monsters chasing Mario in the Nintendo Comics System story The Fish That Should've Gotten Away.
