The ones they use to stuff bean bags with.
Well the problem is, the plastic ball and socket skeleton can only support so much weight and poly pellets are heavier by volume than poly fiber. That and teddy's with that kind of filling feel weird as hell. 😁
I'm probably just going to have to adjust the density of the stuffing a bit to make her less springy and reinforce parts of the skeleton. More tedious than difficult. Either that or rig up some sort of external support for standing. I'll figure something out.
