Cluck, the ranch's head rooster- Hank decides to investigate. However, just as the plot begins to thicken, Pete claims that it was all a joke and that the creature, a Three-Toed Tree Sloth, was really just a porcupine! Fortunately, Hank realizes that that's just what a sneaky cat would say to throw him off the trail, and his continued investigation soon leads him to a strange, bumbling little creature- the Tree Sloth at last! With the finely-tuned instincts of a Head of Ranch Security, Hank realizes that he must arrest this intruder! However, things don't turn out quite like he'd planned, and Hank soon has a very serious problem on his hands...
