Alice is actually quite slim. Real prison clothes do not really flatter the figure.
Bodied yukkuri would normally have 3 stages:
1) the pillsbury dough boy type - called "nudes"
2) typical bodied yukkuri type - fat neck, big head, shiny skin, no nails.
3) human type - pretty similar to humans except with softer skin that seems shinier than normal skin. They still retain hermaphroditic abilities including stalk birth >_>.
Children from bodied yukkuris normally come out as normal baby koyukkuris.
