idea was undead bird-of-paradise amphiptere!
if it isn't clear, their tail is very long, bending over their back and becoming bone-like at the end.
i like natural and/or pastel colors, warrior cats, music, monsters, angels, demons, claws, wings, fangs, expressive body parts, multiple pairs of limbs and long or twisty bodies. if you pick this one, thank you so much !
