Chocolate Breadbug
From Pikmin Fanon
The Chocolate Breadbug is an enemy in Pikmin 3:Return to the Pikmin Planet. It has the general appearance and size of a Breadbug, but it has a square body that is black. Instead of stealing treasures, it will steal enemy corpses and only enemy corpses. When it drags them back to the nest, the enemy will have full health again! Defeat these before you defeat regular Breadbugs so that they don't steal more treasure later.
