|"I'll be the best deputy I can be. Pebblefur would have wanted me to do that."|
|— Acorntail about Pebblefur in Code of the Clans, page 74|
Pebblefur is a tom and an ancient WindClan deputy under the leadership of Featherstar. In Code of the Clans, he dies painfully because of a strange, agonizing lump in his belly. His former apprentice, Acorntail, takes his place as deputy. It is noted that he was well loved by his leader, Featherstar, and Acorntail says that Pebblefur would have wanted him to be the best deputy he could ever be.
