Johnny Test

The agents ask Johnny & Dukey to help them find their deadliest rogue agent - a cuddly robotic puppy, that will set off a neutron bomb if angered! Johnny uses a most unlikely substance to stop the runaway pooch. Johnny hypnotizes Susan and Mary's lab mouse, Montague, to help him get an A+ in Science Class, but a ringmaster kidnaps him from the school to be the star of his rundown circus. The gang saves Montague-and the circus!
