Blankie passes the blocks around and Marty tries to fit them in as fast as he can. No wonder the fire truck is ready in record time!
Of course, they immediately turn on its siren, because there is an emergency, and they have been wanting to try it out for a long time.
Then they extend the ladder all the way to the balcony of the tower room to reach the frightened, screaming princess. Marty puts Blankie's chewed-up hat tip in his mouth and climbs up the ladder.
