Kamemusi
From Sonic Retro
Kamemushi (カメムシ) is a badnik that appears in Sonic the Hedgehog CD's Palmtree Panic. It is not listed in any instruction manual, however it is referred to in the game's source code as Kamemushi, or "stink bug". It resembles a blue Moto Bug, but behaves more like a Crabmeat, stopping occasionally to fire two projectiles.
