Content descriptors: Cartoon Violence

Rating summary: This is an action platformer based on characters from the animated TV show Phineas and Ferb. As players attempt to stop an evil villain from taking over their hometown, they can use laser blasters and whimsical gadgets to defeat “cartoony” enemies (e.g., gelatin monsters, garden gnomes, robots) that blink and disappear when defeated. Some sequences can become more frenetic, with players assuming a third-person view to fire projectiles at waves of flying enemies. During one boss fight, giant robots engage in one-on-one combat to drain each other's health meters; players' robot is sometimes punched repeatedly in the head amid metal clanging effects.
