Surprise Ball

A Surprise Ball (also known as a ! Ball) is a spherical block that Baby Yoshies use during the events of Yoshi's Story. They are round in shape and float in mid air. To use it, the Yoshi must use his tongue on these objects, and they will be pulled in, and thrust upwards, ending up standing on top of it.

Trivia

 * The Surprise Ball greatly resembles the Pitfall from the Animal Crossing series, although the colors are reversed.
