Captain Underpants and the Attack of the Talking Toilets
With Jerome Horwitz holding its Invention Convention, George Beard and Harold Hutchins are forced by Mr. Krupp to stay in study hall all day due to them glueing everyone to their seats the previous year. While getting ready to secretly sabotage everyone's inventions, the two boys run into Melvin Sneedly, working late on his invention, a photocopier that can turn a picture of something into a real being. George and Harold promise not to sabotage it, as long as he doesn't report them. The convention soon has to be called off, and Melvin breaks his promise on purpose and tattles after Krupp is left confused.
