Sonic3&K Badnik Sandworm

Sandworms are yet another offshoot of Dr. Eggman's classic Caterkiller Badniks. First appearing in Sonic & Knuckles, Sandworms would slither through quicksand pits in the Sandopolis Zone, occasionally leaping out to snap at any unwary prey attempting to traverse the desert. They have recently reappeared in both Sonic Colours and Sonic Generations, this time not in any sandy terrain. They also possessed a new attack pattern: they would emerge from hatches in the floors or ceilings and shoot at Sonic with blasters inside their mouthes.
