Plugg is an enemy resembling a walking electrical plug, who originated in Kirby 64: The Crystal Shards. Plugg yields the Spark or Plasma ability when inhaled, depending on the game. It also serves as the Plasma ability's Friend in Kirby Star Allies.
In Kirby 64: The Crystal Shards, Plugg resembles a light, sky blue outlet plug with round, black eyes, yellow prongs, and green feet.
In Kirby Star Allies, it retains its original appearance, though its prongs are now noticeably shorter and has a small screw down the bottom of its back. As a Friend, Plugg wears the crown portion of the Plasma hat, with sparks emanating from its prongs. Like all Friends, Plugg assumes a yellow color scheme as player 2, blue as player 3, and green as player 4.
