Based on the smash video game series by Double Fine Productions (Psychonauts, Broken Age) and the world originally created by Tasha Sounart, Costume Quest is a funny and mysterious animated series aimed at six to 11-year-olds. The show stars four kids facing off against the dark forces lurking in the shadows of their sleepy town of Auburn Pines. To overcome obstacles and achieve their goals, they must learn to unlock and master the magical powers of super-normal costumes-with each costume comes a new set of transformations and powers.
