 He first refused to help Johnny and Dukey about getting rid of the germs (telling that he doesn't do this anymore) but finally decided to help them by making an ingredient that can kill the germs but after Johnny accidentally poured down an "attracting ingredient", it made the germs attack the lab, forcing McPhobe, Johnny and Dukey to escape from the lab and McPhobe destroy the lab with all of the Germs in in.After that, with Hugh's suggestion, he lived with the Test family until his lab was rebuilt.Monty Butterworth
