Clayn is an olive slug enemy that appears only in Kirby's Return to Dream Land. Behaving similarly to Oro from Kirby's Dream Land 3 and Sandman from Kirby 64: The Crystal Shards, this enemy stays burrowed in the ground, rising up when Kirby or his teammates approach. After this, it can easily be defeated by any attack. It never moves from its original spot. It grants no ability when inhaled.
