I have good news - the base for the animation is finished! Roughly speaking 40% of the animation is done, now I need to do the wolf's cumming sequence and polish the whole animation. Thankfully, the polishing stage shouldn't take long as the first part is already polished and the other parts are calmer.
I'm thinking about how I'll make a mimic. Initially, I was planning to make it like a classic fantasy mimic with a tongue, teeth, and tentacles. But now I'm leaning more toward making a creature that occupied this chest. This will remove issues with model clipping and ease my work on creating a model.
