It would be really cool to have a segmented centipede style monster, where you can break off a section and it would split into separate monsters. I imagine this could fit into either the beast or construct families, like a line of scuttlebots connected to each other.
Additionally, a wild boar monsters could be added to the beast family that would primarily do a charging attacks that the player would have to dodge could be fun.
Bumping this in support of the scuttle-pede. Those guys are boring.
