is it a petrified troll?

Looks like an owl that knocked itself out.

I like bm's knocked out owl theory.

Clearly we stumble upon an the ancient ritual of the uu-bugonda tribe, where they lay there wise ones to rest in the oldest tree, so that their spirits will forever watch over the tribe.

I think it's this guy's cousin.

COOL

I vote for a Bad Limb Day.
