It looks pretty smooth, a tad slow, but for people who like the throat bulges that's not a problem :p

Cute. :3

I especially like how Yoshi's tummy bulges slightly at the end. X3

slurp~

I think he needs to poop out an egg next

Looks good so far. Maybe some movement from inside of the belly or make it slightly large if its a large meal

...You must make more of this. More. More. MORE. MOOORRRREEEE

What SHOULD'VE happened to those rabbits in SM64DS. xD

Something a lot of animators for get to do is include little pauses and add variation to the speed of the animation. Two key concepts of animation are anticipation and follow-through. This means that you should lead into every major action with a counter-acting animation. For instance, if someone is going to jump into the air really far they're going to first crouch down quite a bit. The opposite applies to, at the end of every major movement, you need to show recoil or something that was caused by it. Otherwise it will look unnatural.

this was only a test though, not to mention the first true animation ive done

Ok. Keep up the good work I s'pose.

I cant help but just hear the deep gulp noise when he swallows :3
