Turbo and the Super Pet Superhero League think they can lay low for a little while since they defeated Whiskerface and his rat pack . . . but they're wrong! When something goes flying across the classroom while Turbo is jogging on his wheel, he speeds up that jog and sprints into action. Because it's not just something flying across the room. It's a Flying Ninja Squirrel! The Super Pet superhero League must figure what's going on.
