Bubbles
Bubbles is an old Beanish who founded Chuckola Cola, Inc., the distributor of the world-famous Chuckola Cola. He appears in Mario & Luigi: Superstar Saga. According to Bubbles, the key to creating great Chuckola Cola is not merely choosing the best Chuckola Fruit, one also has to tell superb jokes to the brew, allowing the beverage to laugh and carbonate. Bubbles' best soda is his rare Chuckola Reserve, a brew he personally tells the jokes to. However, this Chuckola Reserve turned out to be too good.
When Mario and Luigi arrived in Chucklehuck Woods (or, more specifically, Bubbles' shrine in Mother Chuckalola) to acquire some Chuckola Reserve to save Queen Bean from a Belly Blech Worm-based stomach disease, Bubbles' soda reached perfection, and actually became a living monster, the Chuckolator.
Defeating the soda, Bubbles was so outraged that he pulled a switch, which made the ground underneath them disappear, leaving the Mario Bros. to fall into a cave. If the Bros. are to go back to the woods, they find that Bubbles is no where to be seen. He doesn't appear in the game after this. Bubbles has a brother named Boddle, the president of the Yoshi Fan Club. As seen in the above image, he has an oddly prominent zipper on his back.
