Chop Chop

Chop Chop, called Piranha (ピラーナ) in the Japanese Manual, is a badnik from the 16-bit version of Sonic the Hedgehog 2 found in Aquatic Ruin Zone. Chop Chop is a blue mechanical fish found only underwater that swims faster when the player approaches. They don't have any fighting methods, so it's best to simply jump on their heads to take them out.

The enemy reappeared in Sonic Pocket Adventure's Aquatic Relix Zone, and will be making a return appearance in Sonic the Hedgehog 4 Episode II.
