Grimlord comes up with the idea of turning dog pound pets (and more) into rabid mutant monsters for his own army. Ziktor disguises his voice and pretends to hire Kaitlin to shoot a dog food commercial, knowing that she'll bring Jeb, the first subject to be turned into a mutant. Jeb is slipped a mutating agent and turns into a monster! His first order -- destroy Ryan Steele! Ryan goes to a zoo, where the mutant Jeb is causing havoc. J.B. and Kaitlin are off to find and then destroy the factory that is creating the substance used for the transformation. Grimlord's forces give them some trouble, but they outsmart them. Ryan has Professor Hart send a virtual reality image of a normal dog to the zoo, hoping that the mutant Jeb will recognize what he used to be, and then desire to go back to that state. It works, but not before Grimlord's Toxoid Robot sprays Jeb with a disintegrating agent. Professor Hart saves Jeb from disintegrating.
