Hibernating bears get woken by bizarre and noisy mushrooms in this slyly humorous picture book from the creators of Monty and the Mushrooms that’s perfect for fans of Unicorns Are the Worst! and Fluffy McWhiskers Cuteness Explosion!

Nature is all about balance—and in winter, it’s time to rest. But when a strange blue moon rises in the sky, it brings out the cutest, weirdest mushrooms the forest has ever seen! Their aggressively adorable chatter wakes hibernating bears Glen and Berry.

While Glen worries these peculiar plants and the “mushmoon” that summoned them are a sign nature is out of whack, Berry adopts the vivacious newcomers as pets. With the mushrooms’ motivations murky at best, will they mean the end of Glen and Berry’s friendship—and, possibly, the end of Glen and Berry?
