Still is looking promising from what I am seeing ^.^ Wonder if there will be a pop or not >:3

Looks like the machine is just getting warmed up too ;D

I'm really liking the progression of this series. It's nice to have one going at a slowwer pace than having one involving quick and larger sizes over several frames. You're doing a very good job showing subtle and small increases to his belly size, but also making it look comfortable to a degree. I like how you have him holding his belly now and again have his tail positioned differently. It's really nice seeing you animate the body in each image in small ways, just to make him feel more lifelike and realistic :) Nice work again on his expression and now holding that puzzled/uneasy look within his eyes ;D

Keep it up! =3
