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. In addition, the Penguin Suit lets players swim more efficiently underwater. The penguin suit also grants players the ability to slide on ice and on water without sinking, as well as breaking any blocks they collide with. Traction on ice is greatly improved as well. It is also able to defeat enemies, but will bounce off a sliding Cooligan or a Piranha Plant 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. In the expansion pack, New Super Luigi U, the Penguin Suit made more frequent appearances in courses including some outside Superstar Road. In New Super Mario Bros. U Deluxe, the Penguin Suit can appear as a reward from Enemy Courses. Toadette also possesses the Penguin Suit's swimming abilities, regardless of the form she takes.

The Penguin Suit appears in Puzzle & Dragons: Super Mario Bros. Edition, representing the Water elemental orbs.

Trivia

 * The Penguin Suit functions similar to the Blue Shell from New Super Mario Bros.. Both make the player swim faster, has a Shell Dash-like function and lets the wearer travel on Water. The only differences are that Mario does not go in the opposite direction once he hits a Brick Block, also he cannot slide very long in Penguin form unless he is on ice or on water.
 * 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.
 * In the Super Mario Mash-Up Pack in Minecraft, Diamond Armor is replaced by the Penguin Suit.
