Harold reluctantly agrees to let George hypnotize her, then a local newscast reveals the police are shutting down the company that made the Hypno-Rings because they are now considered dangerous.

The boys, unaware of the newscast, tell Ms. Ribble that she will turn their grades back to normal and not become Wedgie Woman.

That night, she arrives George’s treehouse as the Wicked Wedgie Woman, but accidentally spills super-power juice into her hair, which forms several tiny hands.

When Mr. Krupp snaps at Harold 2000 after he kicks a ball into space, he turns himself into Captain Underpants and asks for help from the robots, whose Spray Starch defeats him.

Due to the counterfeited hair remover, everyone is bald and the boys hypnotize Ms. Ribble to forget the last two weeks and become the nicest teacher in the school's history.
