Like Stay Puft, I had concerns about the ugly pudginess of the body, but trial and error increasing and decreasing worked out pretty well. I have been working a lot lately with open-mouthed characters, and it was fun to insert a tongue this time. I also refined a new technique to make hands that I created when working on Giant Monsters, and I'm super pleased with the outcome.
All in all, I am extremely happy with the way Slimer turned out and wish I could have a copy of him and Stay Puft for my home! Maybe when I have time I can try to make them again for myself or obtain some visiting rights. hahah
