Gellos are an OPEN species, they arent a specified combination of animals so i think it works!!!!! Gellos have white base fur and THREE other colors the gell color are two colors, they can be anything! the skeleton color can either be Yellow, Black, White or Red, all hues of these are okay aswell Gellos can either have bat wings or feathered wings, the gel part is the same as the torso gel, same critiria apply. Pawpads, the spine shapes, and pupils can all either be Hearts (most common), triangles, circles, or just a normal spine! the pelvis (when shown) has that shape in the middle. Blood is whatever the gell color is The ear shapes are simple! they can the three in the drawing! Any markings are okay, however, all SCARS must have a more drained color of the gel the rest is up to you! have fun!!
