Grishells are Gris fused with 'shells' (they have shell-like exoskeletons). They look sort of like red Pacmen. This species of Krawl is first introduced in Spectrobes: Beyond The Portals. This Krawl is powerful and can only be found on the planet Darkmos. When they attack, they open up there shells and smash you between. The property of these difficult Krawl is Corona. The key to killing these peculiar Krawl is to stay away from the spinning shell and then giving it a good smacking with a Flash Spectrobe.
