This model is called the 'Nagi' (which is typically a feminine form of word 'Naga;') a species of mythical serpentine-humanoid creatures residing in caves or underwater, speculated to have full functioning societies of their own- not unlike merfolk.
The inspiration behind this model was to have something beginner friendly that wouldn't pose too much of a challenge, while also still being usable for more experienced toy users. The model features a gentle taper, with a small, knot-like swell towards the base- serpentine, much like it's namesake.
