Barney Bubble

A Barney Bubble is an enemy that appears only in Super Mario World 2: Yoshi's Island and its reissue, Yoshi's Island: Super Mario Advance 3. A Barney Bubble is a purple ball with blue feet, although its artwork depicts it as white with red feet. Its name is a pun on the name of the character from .

Two Barney Bubbles appear in the level Monkeys' Favorite Lake. They quickly run back and forth. The Red Yoshi cannot eat a Barney Bubble, and he can defeat it only by throwing an egg at it. Whenever the Red Yoshi stomps on a Barney Bubble, it produces bubbles, which the Red Yoshi can eat and spit out for a variety of uses. Bubble Dayzees produce the same type of bubble.

In Yoshi's Island: Super Mario Advance 3, two more Barney Bubbles appear in World 6's Secret Stage, Endless World of Yoshis, in the forest area, making a total of four Barney Bubbles.
