Come and hang out with Gumball and Darwin on the roof of Elmore Junior High. The aim of the game is to drop as many items as you can down to your friends – Penny Fitzgerald, Anais Watterson and Tobias Wilson – hanging occasionally out of the windows below. But look out! Sarah G. Lato is slowly advancing up the building with absolutely no chill. Stop her from reaching the roof or it's game over!
