Some of Bear's choices can lead to some frightening scenarios of Bear falling down and hurting or not hurting himself, eating gross things while making a face of disgust, and many intense animal action.
As far as the series goes, it is nowhere near as bad as Man VS Wild was.
Most people shouldn't be too frightened by the wrong choice scenarios or ambience in general, as Bear never really dies and barely gets hurt in a bad way.
Bear sometimes eats gross and very nasty squishy foods that have him in a face of disgust, this may be frightening for some people, but it's nowhere near as bad as Man VS Wild.
