Looking for some body expansion.

Never seen either of those, GREAT finds.
I commend you.

Off the top of my head:
Hanako to Guuwa no Tera (Vol. 3) has a similar expansion, Shadow00000 has it on one of his pages.

And one of Nami's five forms during her Mirage Tempo fight with Kaifun is bloated like that, and there's a short reverse process of it in the animated version of that battle.
