Chip (The Little Engine That Could)

Chip is Tillie's best friend who is a bird. Tom tries to eat him but fails. He supports Tillie in wanting to pull her own train. He does tell her not to worry and not to give up hope. After Tillie was the last engine available to pull The Birthday Train, he sings to Tower "Rock A By Tower in the Trainyard." to keep him from waking up to see Tillie chuff away. After Tillie made it up to the mountain, he congratulated her.
