Alfie is upset when Max and Monty tease him about his size at a demolition site by calling him "small fry" and "half pint." Thomas tells him it does not matter as long as he is useful. Later, when Oliver is demolishing a building, Alfie hears a noise inside and goes to investigate. He finds a cat and her three kittens and rescues them before the wall collapses. The other members of the Pack cheer, even Max and Monty, and from then on, Alfie never complains about being small.
