Derek lead's the march of 11 towards the Stilinski home of course. So when John Stilinski comes home to find a slightly overcrowded puppy pile on Stiles's bed and Stiles's isn't picking up his phone he doesn't know what to do. More than confused he asks Melissa for her assistance in the mystery, where he finally finds out about werewolves. Now it's up to the Sheriff and Melissa to overcome the odds and break the curse before the ever coming lunar moon or else Derek, Stiles, Scott, Allison, Lydia, Jackson, Danny, Isaac, Boyd, Erica and Peter will stay puppies forever.
