With narration of "The Three Little Pigs":
Once there were three little pigs who built three houses (push button and wait [1]).
The first little pig built his house of straw (elevator opens, I get on [1]).
A wolf happened by but the pig would not let him in (door closes [1]).
So the wolf blew the house down and gobbled him up (door opens and is empty, then closes again [2]).
The second little pig built his house of sticks (door opens and I'm in it again [1]).
The wolf happened by but the pig would not let him in (door closes [1]).
So the wolf blew the house down and gobbled him up (door opens and is empty [2]).
The third little pig built his house of bricks (door closes [1]).
When the wolf happened by he huffed and puffed but could not blow the little pig's house down (door opens and I get off the elevator [1]).
