Mudpuddle is a brown-and-white tom.
In Code of the Clans, he is an ancient WindClan deputy under Stonestar's leadership. During a Gathering, when ShadowClan and ThunderClan quarrel about stealing prey, a large tree branch falls, plunging the clearing into a cloud of snow. WindClan's leader, Stonestar, asks if his Clan was all right, and Mudpuddle appears at the far side of the clearing, and reassures his leader that all of the WindClan cats are safe and unharmed.
