A new form Sindri had found by having drank a potion that came from a bad batch and forced his shapeshifting to occur, allowing Sindri to now shift into a synx deer/doe, and now with the sheer tightness and elasticity of this form, they can tightly pack prey down that snug throat to settle in as shapely bulges in that belly, or wherever else there may be to stuff any nearby snacks into, but if they fill their belly enough then it'll start to stretch enough to appear translucent, starting from the front of that tum, with maybe some storage space in that tail to keep any prey and snacks that may be unable to stay in that gut too well during a session of Sindri hastily and gluttonously gorging themselves~..
