In civilised areas, trolls prefer to live in urban areas. They stayed in their favourite habitats until about 40 years ago, after which air conditionning was invented and the forests and mountains were no longer the nicest places to spend summer.
Oh boy, he should not have smacked Kristie on the butt!
Im liking Kristie, she's a little spunky!
Oh trolls and their shenanigans!
Don't worry, these trolls lived with humans long enough to know they're a little fragile and can't be dealt with with a punch in the face... unless you mean to break their face.
Kristie doesn't sound like a face-breaker. He should be fine... at least physically.
