A little update:
1. I inserted the brainy teeth here using a cyanoacrylate super glue. I also used a blow dryer to make the vinyl more workable and found out that this is a dangerous combination. Heat + glue does create some ugly fumes.
2. I am still playing around with this part. I am not sure yet how to integrate the tongue…
3. The teddy bear suits are not tailored to fit but instead actually teddy bears that I found on a local flea market, degutted and customized.
