I remember this comic from a library in the 90s/early 2000s. It was a bunch of kids, possibly classmates, in a small village that would venture out in the woods and pretend to be druids. At one point they accidentally summon a monster without realizing it.
The monster appears later and stalks the village. I remember it looking like some sort of goblin with a short stocky body but long slender arms with wicked claws. I think it was dressed in old dirty furs. The monster was either a demon or some sort of fairy?
I remember a lot of the story being about one of the kids that was shy and chubby.
At one point the monster disembowels an old lady's cat during the night. The remains are found the next day, with strange claw marks on the door.
I think the kids end up fighting it with their druidic powers (maybe they weren't pretend?).
