The school gym is a minor location in The Amazing World of Gumball. It is the place in Elmore Junior High where the students usually partake in gym class. Miss Simian and Mr. Small were formerly the gym coaches, until they were replaced by Coach Russo in "The Coach."
It first appeared in "The Third" when Miss Simian was coaching the students in a game of Trust Ball.
The location appears to be a large open-space gymnasium, allowing the students to perform demanding athletics and play games, like dodgeball, in spread assembly during their class of physical education. The space also provides students to willingly perform extensive workouts (usually weight exercises) at any time they desire. The floor is marked with color-coded lines which guide the players into the correct formation for a desired game.
The school gymnasium also includes bleachers alongside the boundaries of the floor area. Basketball hoops, whose backboards are hanging from the ceiling of the gym, provide height adequately challenging for students to play their basketball games (although, they are never seen actually used).
