Pekka will never dare to eat that. The cow, however, looks more adventurous.
Wow, now that I see a troll against a barn, I can see just how big they are!!
Actually, it's stable, not a barn, and it's leprechaun-built, so no taller than needed to accomodate the cows.
This comic's canon says that trolls are in average eight feet tall, which is pretty big, but not city-stomping big.
But speaking about barns, his still contains two human corpses to get rid of. I hope it doesn't stay off his mind too long, or the task will be even more unpleasant when he gets to it!
