I noticed that you guys were talking about Goo Girls and such? Well, I have been watching a Dev artist,
http://blackmage20.deviantart.com/ whos just done May as a Ditto girl that I think works, heres a link to one pic.
http://www.deviantart.com/deviation/58962923/ In this one hes compareing Ditto May and Zangoose May for voteing compare.
all in all He only does picks of what they would look like as pokemon hybrids or Pokegirls, hes got a few animations that would go in the Body Inflation section, and most of his sequinces and storys are Inflation or body expansion related. Theres also some popping, but its a balloon popping not a body explodeing popping in all cases. (laughing) I do beleave hes a member here, thats how I found his DA, but anyway, just pointing out his Ditto Girl pic sence I saw Slime/Goo Girls in the TF board. (laughing) later. Hail Kane!
