Croctopus is an aquatic enemy in Donkey Kong Country. It comes in two variants coming in blue and yellow or purple and yellow.
Croctopus always chases Donkey and Diddy Kong. The blue and yellow follows them along whatever path they take but the purple and yellow type have a specific path along which they swim. Croctopus rotates as it swims and this makes it very speedy. Even Enguarde cannot defeat it.
