Chirp is a pale gray tabby tom with amber eyes.
In the Power of Three Series
- Chirp returns from hunting with Merry to Jingo talking with the Clan cats. Hussar tells Chirp and Merry to come and meet the Clan cats. Chirp pads over and sits down, but he stays near the door casting anxious glances over his shoulder.
- Later, when Brambleclaw, the leader of patrol that had come all the way from ThunderClan asks whether any of the cats have seen Sol, Chirp says that he hasn't seen the tortoiseshell loner, but he heard that Sol was living with a loner named Purdy.
