AiAi

Aiai is a character from Sonic's sister game, Super Monkey Ball. He has appeared with Sonic several times, notably in Sonic Riders, and SEGA Superstar Tennis.

Personality
Aiai is a monkey who loves bananas. He is usually absent-minded, thinking, "That banana I had was really delicious." Aiai deeply cares for his wife Meemee, his son Baby, and friend Gongon. Despite being absent-minded at times, he is very kind and very brave, going as far as exploring the inside of a volcano on his home island of Monkey Island.

In Sonic Riders
Aiai appears in Sonic Riders, the sequel to Sonic R, as an unlockable character. Oddly enough, he is a Power-type character, and as such, pushes lighter characters around easily. However, due to his small posture, he is easily pushed around just as much.

Physical Appearance
Aiai has similar traits to a Spider Monkey. Although he lacks a tail, he does have an orange shirt with the letter A on it (possibly for Aiai). He has dotted eyes, a small scruff of hair, and rounded ears that stick out of his head. In Super Monkey Ball Banana Blitz and Sega Superstar Tennis, his look was updated, giving him a blue backpack, red oval shaped cheeks, a cat-like smile, and a much sweeter look all in all.
