兩個調皮搗蛋的小男孩喬治與哈洛,他們雖然處處闖禍,喜歡惡作劇,又常常鬧些無厘頭的笑話,讓大人們頭痛不已,不過其實本性一點也不壞。他們最偉大的發明是創造了「內褲超人」。這一回他們惹上的麻煩真的大得不得了,差點在一不小心當中,讓整個星球毀在一群惡魔手裡。這群惡魔就是:邪惡的吃人馬桶!幸好,內褲超人發揮神功,把大家從恐怖的災難裡救了出來。
George and Harold are usually responsible kids -- whenever anything bad happens, George and Harold are usually responsible! This time, their latest prank backfires, and they accidentally invent an army of terrifying talking toilets. Luckily, they know a superhero with enough snap in his waistband to save the day! This looks like another job for the amazing Captain Underpants!
