The models I used in this game are all my own creations from a basic human template, so you won't find them anywhere. But if you do a search for "Wattchewant's Slug" then you'll see the original model on what I based her look on. I've also seen it downloadable in places like sfmlab/smutbase. I'm glad you like mine though as I'm not a professional model maker and so I feel like most of my models are pretty scuffed but hey if people like them then that's great. :)

Saying that they are striped seems exaggerated to me, I mean in the game over animations they move with an almost realistic naturalness, (one more than the others) the truth is that I have the snail girl as my favorite, it may sound strange knowing that she is the monster girl with the appearance that is furthest from human but it gives her her own charm because I prefer a humanoid design more than one that visually is a common human with vague animal characteristics, it gives a fresh air to the design, it is also because I am a fan of the voluptuous green BTW and now that you showed a demonstration video of the remake of this game the truth is that I want to see at least the snail girl in action again
