Supermouse said to Booperman, "Don't punch me or hit me or kill me or kick me." Booperman didn't. Then Supermouse flew off to fight crime. What's he gonna do? He's gonna fight crime. Now he's fighting crime. It means he needs to fight the laughing toilets so he won't get bited, but he has all bones inside so he can't get bited. He has bones that can destroy laughing toilets! The laughing toilets are trying to attack Captain Underpants, but Supermouse just jumps into one and then he doesn't get chomped into pieces, and just saved Captain Underpants. And then he went off to fight crime. And that's the end.
