Red squirrel
From Toadwater Guide
Red Squirrels live on Butternut trees in birdhouses. They can be milked once every day to obtain Squirrel Milk using Milking Gloves. A squirrel has a set number of uses, based on the age of the tree it appeared in and a random factor. Once these have all been utilized, a player must attach a new birdhouse, and wait for it to be populated. Unlike bird usage, you can milk other players' squirrels.
