The Eggheads are a duo of beige-colored eggs that made their first appearance on the School Bus in "The Quest".
The Eggheads are a pair of beige eggs. One of them has glasses and braces, while the other is relatively bare; both have buck teeth and a generally nerdy appearance overall.
The Eggheads are the biggest geeks in Elmore Junior High. They speak with English accents and have an obsession with academics. The two of them are relatively friendly, being sociable enough to attempt to chat with Gumball in "The Genius" and later asking him to be their club president in "The Club". Due to their nerdy way of talking and tendency to use sophisticated words, it is likely that most people don't understand what they are saying, causing them to be social rejects.
