Shell (シェル) is an enemy from Super Ghouls 'n Ghosts. It is found near the end of stage 1 part 1, being dropped in the area by the high waves. Their movements appear dull at first glance, but it is able to use the recoil from the mouth to jump fairly high. While jumping, they spit an eyeball in a straight direction towards Arthur. Shells are immune to damage while closed.
