[The Doctor watches the children sneak away on the flying bus into the other reality, while they wander around the new place full of Halloween creatures that are living day-to-day lives; just like some aliens do. Before finding themselves at grandma's house and turning the lock into a frog on her front gate. Grandma is brewing a potion and they eagerly want to help. Eventually, they do end up help in gathering up ingredients; tooth of a vampire, hair of a werewolf and sweat of a ghost. And then grandma gets turned into a frozen statue inside the movie theatre, of course the children run for it.]

I like this movie makes me think of how aliens and humans are.
