The Witches (1990 movie)
However, Luke is discovered by the witches and they turn him into a mouse. Luke and Bruno (who are both now mice) go to the grandma's room and tell her what happened and they create a plan to defeat the witches. Luke goes into the Grand High Witch's room and steals the potion. He then goes into the hotel kitchen and puts it in the soup that the witches have ordered for dinner. Before dinner, one of the witches, Ms Irvine, decides to stop being evil because the Grand High Witch does not treat her well. At dinner, the witches all eat the soup and turn into mice. The grandma tells Bruno's parents that he is now a mouse and gives him back to them.
