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