Squirrelfur is a red-brown tom and is an ancient SkyClan warrior. In Code of the Clans, when the new leader of SkyClan, Mothpelt, rushes into the river to attack RiverClan, Squirrelfur follows. His eyes are noted to be closed and he appears to be exhausted as he battles weakly to keep himself above the surface of the water. Robinwing, his Clanmate, bites deep into Squirrelfur's scruff, and hauls him onto the shore with the help of the rest of the battle patrol. Maplewhisker then proceeds to grab Squirrelfur's scruff on the other side and keeps a firm hold on him, nodding to confirm she is fine, while Robinwing continues to rescue the other cats.
