Fun little fact, the breed of Wyvern that my dear Raeth takes the form of have crops! I thought it'd be a fun trick to try and keep someone in there for the weekend and then swallow them down on Monday... But that would mean no eating or snacking until then, since the food would just push them right out of the crop and down the throat... I'm not the sort to go that long without at least a snack or few, so I dismissed the idea of holding my prey in that neck-pouch for so long and just gulped them down here and now!

I tried to make the bulge look like it was sinking into his chest there, where the esophagus is further away from the surface and is a bit deeper within the body. Then the bulge returns once it slides into the belly further down :>
