Cooligan

Cooligans are enemies found in the game New Super Mario Bros. Wii. They are blue penguin-like creatures that sport a pair of sunglasses.

''New Super Mario Bros. Wii
These enemies first appear in World 3-1, and appear in ice levels. They are seen sliding and can damage Mario and the others if they run into one of them, although if Mario or anyone else is in the Penguin Suit and they are sliding too, then they will bounce off unhurt. It takes two jumps to defeat one. One jump will knock off a Cooligan's shades, slowing it down. They will also fall down holes rather than hover over them. In this state, if rammed by another Cooligan, they will be defeated.

These creatures can be defeated instantly by a Fire Flower, Star, Ice Flower, Penguin Suit, or Ground Pound. It should be noted though that Cooligans will continue to slide even if they are frozen, allowing the heroes to use them as platforms to reach Star Coins and other objects. They reappear in World 9-5.

Through hacking methods, it is shown that Yoshi can eat Cooligans. However, he lacks the ability to jump on them.

''Mario Party 9
Snowmobiles that look like Cooligans make an appearance in Mob Sleds, from the Wii game Mario Party 9.

Trivia

 * The Cooligan's attack pattern is notably similar to another penguin-based enemy, the Lemguin.
