Allie's Group Height Chart
I actually started this in early March and just sorta forgot about it. While I was streaming yesterday, though, I was at a loss of what sorta SFW stuff to draw, so I got back on this one (and started another). And seeing it now, it makes the proportions of this picture look less wonky.
As with the other height charts, their heights are based on the crown of their heads, not hair/antennae/etc. Router's height is based on her default body type and posture, from belly to crown.
