It came with the package before they got that extra chromosome
cuz they like to play with them
they're just decorations..like on a Christmas tree..

Because all fetuses start off as girls, only later do they change to boys. The nipples form before the switchover.

So we can buy bras and practice.
Because we need something to hang the piercing on
