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 Aquatic Relix Zone from Sonic Pocket Adventure. It also reappeared in Sylvania Castle Zone and White Park Zone from Sonic the Hedgehog 4 Episode II, this time with the addition of eyes.
