Sebastian the ash tree lives in a forest of magic and wonder alongside his one true love, Marion the boulder. But things take a frightful turn when an invading enemy threatens the susceptible ash trees of the forest. Can Sebastian's friends the fungi and their underground network of filaments help him survive the battle?

With a ragtag army of forest creatures at his side, each with their own place in the delicate balance of the ecosystem, he might just survive the attack.

Come with us to Sebastian's wondrous world and hear the magical (and very silly) forest tales along the way.
