Join the Cutie Mark Crusaders as they embark on another mystery filled with action and adventure when a trip to the woods leads them to discover it’s filled with trash!

What could be causing this mess and what can they do about it? It looks like another mystery that Apple Bloom, Scootaloo, and Sweetie Belle will have to solve, but one where not everything is as it seems. Ponies start seeing weird shapes, hearing unknown sounds, and losing things, but it couldn’t actually be the Spirit of the Forest, right?
