A feel-good picture book about best friendship told with dry comedy and an open ending-squirrel and mushroom are best friends until another best friend (a fly) comes to play.

"In this funny picture book exploring a forever childhood question about friendship, squirrel and a mushroom explore the forest through the seasons, show each other special trees, build snow mushrooms, share the good times and bad which become good bad times alongside a friend. Then spring arrives, and so does a new friend. And then another. This raises a profound question for an overthinking squirrel: should we have just one best friend?"--Provided by publisher.
