This man encountered the Trickster in his own domain. In the woods this spirit isn't acting out of simple mischievousness. In the woods he has something to protect and any human that gets too close won't be allowed to leave. At least not as a human.

The man's body grew rounder. The tone he had spent years on dissipated. His muscles however became stronger than ever. His shirt all but gone, his pants began to shred as well.
