ALVINNN!!! and the Chipmunks 2015 Season 3 Episode 18 Pack Animal / The Haunted Getaway Episode Title: Pack Animal / The Haunted Getaway Episode Description: Pack Animal:Simon has a hoarding problem, so Dave tells him to start cleaning house and get rid of his old inventions that he does not use anymore. It takes him all day and night, but Simon manages to fill two boxes: one of inventions to keep, and another of inventions that can be discarded. Unfortunately, Theodore accidentally donates the wrong box to a thrift store, where Simon's more dangerous and unstable inventions quickly sell, causing all sorts of mayhem for the consumers that have bought them - the most dangerous of which is a black hole device purchased by Basil. After Basil, the Chipmunks, the Chipettes, and other items are sucked into the black hole, Simon must quickly reverse its pull to send them all back down to Earth. The Haunted Getaway:Dave takes the boys to a cabin in the woods for the weekend, but has made it perfectly clear to Alvin that he cannot mention anything about the cabin being haunted, citing a previous incident where Alvin's teasing gave Theodore a complex. To make matters worse, Alvin begins witnessing and experiencing all sorts of spooky happenings in the cabin, such as ghosts peering through windows, closet doors opening and closing, lights flickering, and furniture moving independently. Convinced that he is up to his old pranks again, Dave completely shoots down each of Alvin's attempts to tell the others what is going on to prevent Theodore from being scared. It is not until Alvin enters a restricted shed on the property that he discovers that everything was staged by a pair of people producing a prank reality show, and that he was their latest victim.
