Porcupuffer

Porcu-Puffers appeared in Super Mario World, where they would follow Mario and Luigi in the water. The Mario Bros. could perform the Spin Jump on them to "ride" them, or use Yoshi. They resemble giant Cheep-Cheeps with blue spikes all over their backs.

They appear in two levels, the secret level on top of the Vanilla Dome, and a secret area in the Cookie Mountain level. They also appear in a secret area from Chocolate Island 1.

A similar species called Puffer-Cheeps appeared in Mario & Luigi: Superstar Saga.
