Bubble Mario

Bubble Mario is the form that Mario takes when he uses a Bubble Flower in Super Mario Bros. Wonder. While in this form, the player can blow bubbles that follow a straight path unless they get drawn to an enemy. Bubbles that hit enemies trap and transform them into a coin. Unlike Fireballs, bubbles can go through walls and defeat enemies that normally cannot be defeated such as Dry Bones. The player can also jump off of them. These abilities are similar to those of the Bubble Baby Yoshis in New Super Mario Bros. U.

Bubble Mario wears a pink hat and shirt with red overalls, similar to the overalls given to Fire Mario and Ice Mario. Bubble Luigi is the same, except his overalls turn green. For both Bubble Blue Toad and Bubble Yellow Toad their spots will become purple while the white part of their head will become blue and yellow respectively and their pants also become purple. Bubble Toadette's colors are the same as Fire Toadette, simply replacing the red on her cap, vest, and pants with purple, while the round spots and dress turn pink. Unlike Fire Peach's, Bubble Peach's colors keeps the original pink on her panniers, collar, and frill, while her dress and heels become purple.

Bubble Mario's colors closely resemble Luigi's pink alternate color from the Super Smash Bros. series, which is referred to as "Strawberry Luigi" on the original Super Smash Bros. website.
