The mods took her a long time, and the creature she based them off of was one she had created a number of years ago. ^^ I'm quite sure she thought it through plenty before putting drill to resin.

Also, her Chiwoo could be modded back to a more normal state, if she so chose. I'm sure, after doing something that skilled, she'd be able to fill in the space with epoxy putty and sand it to resemble a whole chest.
