Murphy attempts to trap Puck with a pair of handcuffs. One end is already clasped to Murphy’s wrist when he slyly approaches Puck. But he accidentally snaps the other cuff to… El Roacho. Puck nabs the keys and darts away. Murphy and El Roacho, cuffed together, race after Puck while they desperately try to break the links between them. They are successively flattened, electrocuted and even encapsulated.
El Roacho has the brilliant idea of training his dog Rex to chase Puck. In order to train the dog he decides to disguise a Pester and then a marionette as Puck. After several tries, El Roacho thinks he has succeeded and orders Rex to hunt down Puck!
Due to a short circuit in his Palm, Murphy comes up on El Roacho’s list of specimens to capture. In order to escape El Roacho, but also aiming to capture Puck, Murphy creates a machine that makes him invisible. There’s only one hitch. The machine doesn’t work very well. Every time Murphy becomes “invisible” and Puck is within reach, a new problem crops up.
