Marvin wakes up returned to his normal life, with no memory of the prior events, and more full of life than he's ever been. However, there is something different about him. He can outrun horses, and mean dogs are afraid of him. Attributing it to his excessive purchasing of "Badger milk," he doesn't worry himself. He decides to go to the park, and while he is there, he meets Rianna (Played by Colleen Haskell) while she's out walking dogs from her animal shelter. His animal instincts begin to take over, and he begins to act like an animal in front of her.
More days go by, and Marvin's senses begin to get stronger, and he's often waking up in strange places. He now chases cats, and destroys property because of his instincts, and because of it, he gets fired. As Marvin's instincts get stronger, he must find a way to try and control himself to fit into the everyday world.
