Lily is Snail's mother and she appeared in Code of Honor when the Strongbranches helped the rest of the Brightforest Troop to traverse the flooded waters of the Tall Trees in order to find a new home. Lily handed Snail to Thorn and asked him to protect her and he said he would. When Lily was on the other side of the rushing stream, Snail tried to cross as well, but fell in the water. Thorn and Frog rescued her by diving in the water and hauling her out, pushing her towards the other side. Lily hugged Snail in relief that she was not harmed and the Strongbranches were praised for their bravery.
