My 8 year old sister got bit by my juvenile BP a few years ago - not only did it tag her, but it latched on and wrapped . I've asked her about it since and she said it really just felt like a hard pinch, that it scared her but after the initial impact/pressure it wasn't super painful. She definitely had a little bit of a bruise going and some teeth marks leftover afterward though

I've never been bit but I'm very competitive with my sister... if she can take it, I can take it!
