Clu Clu Land Nintendo

Clu Clu Land stars a fish named Bubbles. Bubbles is a "bubble fish" whose only goal is to swim through a maze, collecting gold and dodging enemies. To collect this gold, Bubbles has to use certain posts that can turn him around. These are located at intervals throughout each level (only a few pixels apart), and are just wide enough for Bubbles to fit through. The enemies, Unira, can be stunned if Bubbles uses an attack, and then pushed into a wall to kill them.
