How do you fatten/inflate Skeleton Women?

Boo! Happy Cinco de Mayo, everyone! I know I'm a tad late with things, but I've been going through some troubles lately and it's been keeping me from drawing. But reassured, things are looking a bit better, but I can't say for sure. I know I have some commissions to finish and I want to say to those who have been putting up with this that I am truly sorry. I will work and hopefully finish them by the first half of June. And once I do finish them, I'll try to make it up to you guys, okay? 

Anyways, I've been working on this since last October and I've been working on it on and off. I really loved the designs of "The Book of Life" since they were revealed last year. And I got to watching the movie this month and I have to say it was good! Not that great, but good. I really, really loved the visuals and it was just pure eye candy! Anyways, here you see the twins; Adelita and Scardelita, expanded of course. I found their designs really attractive and of course I had to draw them expanded! So you have Adelita (left) eating some really tasty churros and getting a bit pudgy! And Scardelita (right) has inexplicably inflated.

I will also be updating this with more details to the twins and a background, but first those commissions. 'Kay now, bye!  

EDIT: I've have updated this deviation with the newly revamped image that was used in my latest submission.
