Flotsam

Floatsam is an enemy from Rusty Bucket Bay in Banjo-Kazooie. It hangs on the walls of The Rusty Bucket and disguises itself as a flotation ring, springing to life if Banjo and Kazooie get too close and bouncing after them.

Although its bright colors make it relatively easy to spot, it can be hard to avoid if you round a corner and one happens to be there. Interesting enough, this enemy is immune to the Beak Bomb ability.

The best way to deal with them is simply attacking them with a well-timed Rat-a-tat Rap. When defeated, the Floatsam will commically deflate before vanishing.
