Bumpty

Bumpties are a race of penguin-like creatures that first appeared in Super Mario World 2: Yoshi's Island. They are usually found in icy regions. Most Bumpties are blue, however pink and green individuals were shown in Paper Mario.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Bumpties are usually found wandering around in icy areas of Yoshi's Island in their debut game, Super Mario World 2: Yoshi's Island. While Yoshi can grab Bumpties with his tongue, he cannot eat them. Also, if he runs into one, he is bumped backwards, hence the name. This means that Bumpties can't hurt Yoshi.

They can also steal Baby Mario if Baby Mario has already been knocked off Yoshi and is floating towards one, like a Bandit.

Tetris Attack
A certain Bumpty appears in Tetris Attack, allied with Dr. Freezegood. In here, he is depicted as Yoshi's friend, but enchanted by Bowser and his minions to work for him. Yoshi and Bumpty become friends again after freeing him and Dr. Freezegood from the spell. He also notes in the game, that others say that he's cute, but he really doesn't like it, and would like to be said as cool.

Note that Bumpty only appears in the SNES version of Tetris Attack. He does not appear in the Game Boy version.

Yoshi's Story
Bumpties reappear in Stage 3-4: Frustration in Yoshi's Story. They still repel Yoshi if run into, but they can be eaten.

Yoshi's Island DS
They also appear in Yoshi's Island DS in Baby Bowser's levels. Here they can be defeated simply by blasting them with one of Baby Bowser's fireballs.

Yoshi's New Island
In Yoshi's New Island, Bumpties appear in World 5-1, Brave the Bumpty Blizzard. They are colored purple instead of blue.

Paper Mario series
Bumpties in the Paper Mario series are referred to as penguins.

Paper Mario
Bumpties return in Paper Mario. In this game, Mario travels to a city of Bumpties called Shiver City. He also meets a famous writer named Herringway who is a Bumpty. In this game all the Bumpties are allies, not enemies. A small group of Bumpties (Including Mayor Penguin) appear in Princess Peach's Castle prior to the arrival of Bowser.

Paper Mario: The Thousand-Year Door
Bumpties also make a small appearance in Paper Mario: The Thousand-Year Door where they live in Poshley Heights, a town of the rich and famous. Mario also meets an incompetent detective Bumpty named Pennington.

Super Mario Advance 4: Super Mario Bros. 3
Bumpties also appear in Super Mario Advance 4: Super Mario Bros. 3, only appearing in the Japan-Only Level Tā-kun ni Ki o Tsukero. The sprites are exactly the same as in Yoshi's Island. Players can not harm them unless they use a Fire Flower or Hammer Suit. If players try stomping on it, they are bounced off, and if they touch it from the side, players will not be harmed, but they will be knocked off to the side.

Trivia

 * The name Bumpty is a corruption of bumpy, referring to its bouncy, rubbery feathers.
 * Oddly, the official wallpaper of World 5 from Yoshi's Island released by Nintendo features the official artwork of a Raven, but recolored to resemble a Bumpty.
 * The Cooligan enemy in New Super Mario Bros. Wii is very similar to the Bumpty in that they are both Penguin enemies encountered in Ice stages. The Penguin Suit power-up also resembles the Bumpties. However, Cooligans can hurt the player, which is something that the Bumpties aren't capable of.
