Rappy

A Rappy.

The Rappy is an enemy from the game Donkey Kong on the Game Boy. It appears in stage 1-1 in the Big City for the first time, which is after stage 0. Rappies only walk horizontally on their platform and turn around when they reach an edge or run into another Rappy. They do not attempt to charge at Mario, but they kill him if he runs into them. Standing on them is possible, and they can be picked up and thrown at other enemies. If Mario approaches them with the hammer, they run in panic into the direction they are currently facing, which might actually bring them closer to Mario.
