Thunderrose

Thunderrose is a tall, light calico she-cat.

Book 1
Thunderrose appears in Robinfleck's patrol, along with Pebblestreak and Birchpoppy. They encounter a kittypet at the border named Speckle. Robinfleck has a chat with Speckle, and she mentions talking to Birchpoppy, to his surprise. Robinfleck asks if that was true, but Thunderrose interuppts, saying that Speckle is just a weak kittypet, and that they should forget about it. The patrol then leaves, Birchpoppy saying nothing to Speckle.

Thunderrose is surprised when Flame and Willow announce themselves as Speckle's kits. She is the one to suspect that Birchpoppy is the father, and she is correct.

She and Cricketsong are closer than usual, as they are revealed to be mates when Thunderrose bears two she-kits, Mothkit and Sparkkit.
