Penguin Suit

The Penguin Suit is an item found in the game New Super Mario Bros. Wii. As the name suggests, it is a suit that resembles a penguin. This item first appears in World 3, and from then on it can found in Toad Houses as well. The suit allows players to turn into their Penguin form, that has a blue or black body with short, colored trousers. It also gives players the ability to throw Ice Balls at enemies, freezing them (just like the Ice Flower); allowing the frozen enemies to be used as platforms. It also improves traction, making players not slip while on ice. In addition, the Penguin Suit lets players swim more efficiently underwater, and even slide on ice and water without sinking or breaking any blocks they collide with. It is also able to defeat enemies, but will bounce off a sliding Cooligan unhurt. It is introduced along with the Propeller Mushroom as the newest power-ups in the game.

The Penguin Suit reappears in New Super Mario Bros. U and acts the same way it did in New Super Mario Bros. Wii, though the player must get it through a Power-Up Toad House in Superstar Road. Additionally, Penguin Bowling allows use of the Penguin Suit. It can also be used in the Penguin Pack from Boost Rush Mode.

Trivia

 * The Penguin Suit seems to mimic the shell dash function of the Blue Shell from New Super Mario Bros. as both items allow the wearer to slide along surfaces at faster speeds than running.
 * The Penguin Suit is also similar to the Frog Suit of Super Mario Bros. 3, allowing the player more control in the water.
 * The Penguin Suit is rather similar to the penguin suit in the Wii Fit game "Penguin Slide".
 * When a character obtains a Penguin Suit, the sound effect is slightly different from other power-ups. A sound similar to a duck quacking is played along with the normal power-up sound.
