Synopsis
When Melvin gets kidnapped by the Biglyans, the schoolship goes on a mission to save him. All the cryo-chambers in the ship are set for three months to prevent awake crewmates from going insane. However, Krupp set his for three hours because he wanted to be the captain of the ship. Since he's the only one awake, he decides to wake up George and Harold so he can boss them around.

Summary
Melvin is kidnapped by the Biglyans, and the schoolship goes on a mission to save him. The class, teachers and the space crew are set in cryo-chambers, which has been set for three months (due to space craziness prevention).

However, Krupp set his chamber for three hours because he wanted to be the captain of the ship. Since he is the only one awake, he decides to wake up George and Harold so he can boss them around. Unfortunately for Krupp, they refuse to be his minions. They all agree to divide the ship into two halves; one for George and Harold and one for Krupp.

After a few hours of doing pranks and writing a comic, the boys and Krupp hear a sound coming from the middle of the ship. The boys and Krupp think that each other are going space crazy, with them running toward each other, and the three run into the PE room, where they crash into each other, finding Dressy up in the air, floating. It turns out, that during a conversation between the boys and Krupp about them refusing to be Krupp's minions, George rolled a tire down the stairs into a special liquid that bounced onto Dressy's chamber, making her the Hangry Hypnosinger.

The boys snap their fingers, turning Krupp into Captain Underpants, who battles with the Hypnosinger.
