They apparently are/can be cannibalistic.
which hasn't yet come up in the Redcaps game, they just eat "interesting" things like long dead rats and Dettol, meanwhile in Mercenaries 13yo's character has had a couple of opportunities and taken them x_x
Overprotective Redcaps are also terrifying given the vivid descriptions the kids gave me when I was discussing potential story ideas with them XD So if this picture had any narrative behind it, they are probably just being intimidating and haven't started or finished anything yet otherwise the child would be in the middle of the group rather than up on dad's shoulder (she's very non-martial which is a weird kind of character for me to play), so no blood yet and I don't want to draw a Redcap fight, they're messy XD
