When Stu is locked up, Hypnos later visits the jail cells, where Stu finds himself locked up with Attila the Hun, Jack the Ripper, and Stephen King, who reveals his nightmare of Cujo pulled the same trick Monkeybone pulled on Stu. Hypnos explains to Stu that he plans to use Stu's body to get a chemical substance named Oneirix that Julie developed that gives people and animals nightmares, which gives him more power. Upon being sent to the institute by Hypnos upon reminding him of his mission, Monkeybone (in Stu's body) ends up successfully stealing the Oneirix, switching it with another juice. Monkeybone obtains the Oneirix and puts it inside stuffed monkey toys of himself (Monkeybone) so that those who touch them will be infected and given nightmares. With help from Miss Kitty, Stu escapes from his imprisonment.
