Prince Frog is convinced he’s destined to rule the world … the trouble is, the world has ended. Undeterred, Frog sets out to claim his crown, armed with nothing more than a pair of Catastrophe Pants and his trusty stick, Basil Rathbone. But Frog soon realizes that the world isn’t quite as ended as he thought. He discovers a magical kingdom, filled with wild landscapes, strange creatures … and a princess sitting on his throne. Together with his new friend, Sheriff Explosion the sheep, Frog seeks to prove his princeliness and escape the clutches of the princess who’s sure he’d make a better pet than a prince. But just when Frog thinks things can’t get any worse, he discovers he is actually the prince of an invading alien army and that he’s just given the go-ahead for an all-out alien invasion. Can he and the princess put aside their differences long enough to save the kingdom – and the world?
