Porcupuffer

Porcupuffers  (alternatively Porcu-Puffers ) are a species of large, garishly-colored Cheep Cheeps that first debuted in Super Mario World. They resemble gigantic indigo Cheep Cheeps with magenta lips and blue, cyan, and yellow spikes all over their back. Their faces are nearly identical to those of Boss Basses and Cheep Chomps, but unlike them, they never try to eat Mario. Their name is a portmanteau of "porcupine" and "".

Super Mario World
Porcu-Puffers appear in Super Mario World, where they follow Mario and Luigi in the water. The Mario Bros. can perform the Spin Jump on them to "ride" them, or use Yoshi. They appear in three levels: the third secret level on top of the Vanilla Dome, a secret area in the Cookie Mountain level, and a hidden area within Chocolate Island 1. Unlike the Floating Mines, they are vulnerable to fireballs. The in-game sprite depicts them with magenta lips while the artwork depicts them with yellow lips.

New Super Mario Bros. Wii
After a long absence, Porcupuffers are featured again in New Super Mario Bros. Wii. Here, they attack exactly the same as the Spike Bass in the predecessor, swimming near the surface to pursue the plumber and his party or even leaping from the water to attack. Porcupuffers serve as obstacles for World 4, and they appear again in World 6-5 and later in World 9-2. They can only be defeated with a fireball, star or Koopa Shell; another one will come to take its place several seconds later. This also occurs in the Enemy Courses, although the replacement occurs much quicker. They can also be frozen, but they crack out almost instantly, much like a Spiny Cheep Cheep.

Super Mario 3D Land
Porcupuffers later appear in Super Mario 3D Land, inhabiting underwater and beach levels. They retain their appearance from New Super Mario Bros. Wii. In this game, Porcupuffers swim back and forth while underwater, while in World 6-1, they jump out of the water in specific locations attempting to hurt Mario, and may even break some portions of the bridge he uses to reach the end of the level. Aside from the bridge-breaking, these behaviors are shared by this game's Cheep Cheeps, making them functionally similar to a Big Cheep Cheep in this game, albeit with spikes.
