S1·E37 Three Wishes

Peter eagerly awaits the passing of a shooting star so that he can be granted three wishes. But Hook hears about the star's magic and recites the rhyme to call its power at the same time as Peter. The two enemies decide to split their wishes, each getting one and a half, but the half wishes are granted first and don't turn out quite right. When the adventure takes a fatal turn for Hook, Peter uses his full wish to make sure the whole thing never happened.
