Alfie is upset when the rest of the Pack tease him about his size at a demolition site. 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. The other machines cheered, even Max and Monty, and from then on Alfie never complained about being small.
