Salamence ate something that caused them to rapidly fill up with air. Their body continually expanding with air as their head starts to sink into their ginormous puffy body. Unfortunately for Salamence, it does not look like they can get this air out. They better get used to being this big, round, and puffy!

This was my first air inflation ever! I hope it turned out well. I thought Salamence was a good first choice to practice, with those side horn things pressing into the neck.
