Flotsam

Floatsam is an enemy from Rusty Bucket Bay in Banjo-Kazooie. It hangs on the wall and disguises itself as flotation ring, springing to life if Banjo gets too close and bouncing after him. Although its bright colors make it easy to spot, it can be hard to avoid if you round a corner and one happens to be there. Interestingly, this enemy is immune to the Beak Bomb ability.
