A Porcu-Puffer is an enemy in New Super Mario Bros. Wii. They are blue puffer fish with giant, pink lips and a spiky back. Porcu-Puffers first appeared in World 4 (NSMB Wii). They are World 4's Enemy Course enemies. On the map, a Porcu-Puffer appears near the wooden bridge. When Mario nears the bridge, they will jump on Mario. He would then have to enter the Enemy Course. The Porcu-Puffer swims and jumps at Mario. Mario must avoid the Porcu-Puffer, while trying to get the Toad Balloons. Porcu-Puffers attack Mario by trying to jump on him. Porcu-Puffers can damage Mario if he touches them. To defeat a Porcu-Puffer, ram into it with a Starman or fire a Fireball at it using the Fire Flower's powers. They cannot be frozen, for they will break out once the iceball touches them, much like with Spiny Cheep-Cheeps. Porcu-Puffers also make an appearance in World 6-5 and World 9-2. Porcu-Puffers also appear in Super Mario Galaxy and Super Mario Galaxy 2 as extremely rare enemies. In Super Mario Galaxy, it appears in the Drip Drop Galaxy in a hidden Treasure Chest underwater. If the Treasure Chest is opened by throwing a Green Shell at it, the Porcu-Puffer will come out. In Super Mario Galaxy 2, one appears in the Cosmic Cove Galaxy. It will swim towards Mario/Luigi trying to ram into them. If Mario/Luigi touches a Porcu-Puffer, they will lose one wedge of health from their Health Meter. In Mario & Sonic at the London 2012 Olympic Games, Porcu-Puffers appear during the event, Dream Rafting. There is a task in the event where a team is required to defeat the Porcu-Puffers. To defeat the Porcu-Puffers, all characters must Ground Pound the raft at the same time when one is beneath it. They also appear in the Highway Tally game in the London Party mode.
- Their name is a portmanteau of "porcupine" and "puffer" (puffer fish).
- In both Super Mario Galaxy and its sequel (Super Mario Galaxy 2), Porcu-Puffers tend to disappear after a short while. This makes them even rarer than they are since they only appear as temporary enemies instead of permanent enemies like most other enemies. .
