Ultra Pukupuku

Ultra Pukupuku (ウルトラプクプク, Urutora Pukupuku, Ultra Cheep Cheep) is a powerful Cheep Cheep from the Special Zone level Mondo, that only appears in Super Mario-kun.

While traversing the Mondo level, Mario, Luigi and Yoshi are pestered by a pesky normal-looking Cheep Cheep. While the fish keeps giving them a bad time while underwater, he then grasps for air every time the tides lower, so Yoshi and Mario finds the cork in a pit and remove it, draining the level from all the water. The Cheep Cheep grasps and flips around until he suddenly grows feet and becomes bigger, revealing to be a powerful Cheep Cheep known as Ultra Pukupuku, whose real power was refrained by the water. Mario attempts to hurt him with a cape twirl but fails and is launched in a rock, where he finds a 3-Up Moon, becoming 3UP Mario. Using the moon on his cap as a fishing hook, Mario hooks up the Ultra Pukupuku and zaps him with an energetic ray that turns him into the size of a goldfish.
