Boulderfur

Boulderfur is a large, pale gray tom.

The Fourth Apprentice

 * Boulderpaw does not formally appear in The Fourth Apprentice, but is listed in the allegiances. His mentor is shown to be Breezepelt.

The Forgotten Warrior

 * Boulderpaw is with Breezepelt, Heathertail, and Furzepaw when they meet Birchfall and Ivypool at the stream. They demand to know why they are in WindClan's territory in the first place, despite the stream not being owned by either Clan. When Heathertail asks Furzepaw why she is hanging back from the dispute, Boulderpaw says that he'll fight the ThunderClan cats, but Breezepelt tells him that it isn't a battle worth fighting for.

The Last Hope

 * He now has his warrior name of Boulderfur. Boulderfur is seen battling Thistleclaw in a flurry of claws, before he is pounced on by another Dark Forest warrior and pushed down to the earth. He is later seen being told to go back to camp after the battle with the Dark Forest.
