Captain Underpants and The attack of the Talking Toilets by Dav Pickley
Captain Underpants and The attack of the Talking Toilets is about two boys Clyde and Harold, they wanted to join the invention convention but Mr.Krupp wouldn't let them because last year they ruined the convention.So Mr. Krupp put them in detention for the rest of the day of the Invention Convention. The night before they broke into the gym and messed with the projects and thought they could get away with it, but Melvin Seedly tattled on them.. While in detention, the boys wrote a comic about the attack of the talking toilets and went to the gym to copy it on the Patsy 2000 which they thought was a photocopier, but it makes things 3D. The school was taken over by toilets that only one person could stop - Mr Krupp. When you snap your fingers he becomes Captain Underpants and saves the day because of Harold and Clyde. They were named heroes because they made a deal with Mr.Krupp that they would fix the school and not tell anyone he is Captain Underpants.
