The two crabs move in opposite directions (left and right). They can not move up and down. When they spot Bomberman, they stop and create a vertical line of bubbles, which harm Bomberman on impact and erase bombs. When the two crabs are sitting down, they are vulnerable to targets. After 2 hits, they spawn up to four coral-enemies at a time. They require 5 hits to be defeated. After their defeat, Bomberman recoveres the fifth chip.
- In screenshots of The Cockle Twins defeated, the Japanese version of Bomberman '93, originally Bomberman appears riding a Cockle with a beer mug and one kani kama in your hands. In the American version, Bomberman appears walking Cockle with nothing in hand.
