The Pearly Clamclamp is an enemy in the Pikmin games. It looks nothing more than a clam with a pearl inside it. The pearl is its core, surrounded by a blue membrane. When Pikmin approach it, it will open its shell to reveal its core, but will close down after a few seconds, eating all Pikmin attacking it. When it is killed, be sure to get the pearl, as it will make a whopping 50 Pikmin when carried to the Onion.
