I am working on stats for the Three Billy Goats Gruff, who, having defeated the troll, now guard the bridge against anyone wishing to cross over.: they wanted to cross the bridge in the first place because the meadow on the other side was greener and more lush than the meadow on their side, but having gotten across, they realized the new meadow wasn't as good as it looked, and maybe the grass was actually greener on the other side.... They are now all full grown, though the older brother is getting a touch arthritic (which makes him very irascible) and the younger one is impetuous and a bit of a braggart. They want both meadows, but can only be on one side or the other: if they are on the same side as the kids, they will challenge them; it they are on the other side, they will charge them.
There are no stats for a goat-sized creature, as they are somewhere between a dog and a cow. I was thinking of using the base stats for a horse and revising them downward; or should I use the stats for the dog and boost them? They have the "butt" ability - by lowering their head and charging, they inflict +1 wound.
Any other ideas?
