Gyotot

Gyotot (ギョットット) is a fish-like robot enemy in Mega Man 4. It mainly appears in Toad Man's stage (near the end of the stage) and Dive Man's stage (near the beginning). If Mega Man is on a platform or nearby, Gyotot will leap out of the water to attack.

In Ruby-Spears' Mega Man cartoon show episode titled "Robosaur Park", Dr. Wily launches a group of flying Gyotot-like robots to pick up Proto Man, Cut Man, Guts Man and Toad Man after their defeat.
