Acorn, labeled The useless is a male contestant in Mystique Island who was placed on team Red.
Due to being a pretty slow competitor (when it comes to running, swimming and even falling), most of his teammates consider him as useless. He is also having difficulties to develop himself, because he spends too much time being overhauled and controlled by his father, Bush. He's also known for having large teeth. He tends to make animal voices when he tries to speak.
- He is son of Bush.
