Completely on his own, the well-meaning beaver, Wooden Head, decides to support the community's efforts to reinforce the dam by cutting down a large tree, unbeknownst to him that a mother bird is there. Now, her nest is floating down the river, and, eventually, it runs aground a dark underground cavern occupied by an irascible wolverine who's taking a nap. Can Yakari with the help of a kind bat save the brood?
