Bubble Monkey is a character in EarthBound. He is a monkey who first appears in the Winters drugstore when the player first takes control of Jeff Andonuts. If Jeff gives him bubble gum, the monkey will join Jeff, and will be able to float over certain obstacles, including allowing you to ride Tessie . He leaves Jeff for a female monkey near the end of Jeff's story arc, but appears later in the game when Ness and his friends travel through Winters. He also has a sense of humor.
- Bubble Monkey's equivalent in EarthBound's sequel, Mother 3, is said to be Salsa. Both Bubble Monkey and Salsa share similar roles in their corresponding games, in addition to having similar appearances. These similarities extend to both characters assisting a particular main protagonist in some way, and that both ultimately find a girlfriend sometime after being introduced.
- The localization team changed Balloon Monkey's name to Bubble Monkey when translating MOTHER 2, but they made a few errors; several times during the main script, he is mistakenly referred to as Balloon Monkey. Thus, some people refer to him as such.
- Bubble Monkey is also known as Chewing Gum Monkey.
