Nemo

Nemos are aquatic enemies encountered in Donkey Kong Land. They only appear in the level, Nautilus Chase. The title of the level refers to Nemos as "nautiluses", despite the species more closely resembling the now extinct ammonites.

Unlike Croctopuses, who simply follow a set path, Nemos actually chase Donkey Kong and Diddy Kong throughout the level. When they are first encountered, they appear to be sleeping, but will soon emerge from their shells as the monkeys pass by. The Nemo will then follow behind them at a fast pace through the coral-filled level. If they are not fast enough, the enemy will attack the Kongs. These foes can be hard to avoid sometimes, as they can not be defeated and do move quite fast, even in tight spaces. At some point however, the Nemos will stop running after the heroes, and huddle back up in a corner somewhere around the coral.

The name of this species comes from Captain Nemo, who pilots the Nautilus submarine in the science fiction novel, Twenty Thousand Leagues Under the Sea.
