Balloon Baby Yoshi

Balloon Baby Yoshi is a magenta Baby Yoshi appearing in New Super Mario Bros. U. It allows the player to reach higher places by inflating like a balloon when the player shakes the Wii Remote or presses the button on the Wii U GamePad. Balloon Baby Yoshis can inflate to a maximum of seven times, and will deflate afterwards or when the player lands.

Trivia

 * Balloon Baby Yoshi is very similar to Blimp Yoshi from Super Mario Galaxy 2, except that the latter has a time limit rather than an input limit.
