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

After a long hiatus, these enemies reappear in the game New Super Mario Bros. Wii. Here, they attack exactly the same as Spike Bass. Porcu Puffers serve as obstacles for World 4, and they appear again in World 6 in level 6-5 and later in World 9 in level 9-2.

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