I adopted this babe from  tumble-tart recently who also drew this ref sheet you should go watch them!

This is Illusive (though she likes the nickname Firework), she's from the same "universe" as Caligo? and much like him, she can travel seamlessly from dimension to dimension. She has a tendency to accidentally leave parts behind when she's warping to a new plane of existence so her appearance can be somewhat alarming (if she shows up somewhere, for instance, as only a single disembodied arm or sans a head).

She is very bubbly and happy and likes wrapping others in her big fluffy tail and annoying her best friend Caligo?. She also is also slightly mischievous likes weirding others out by twisting herself and her limbs into unnatural shapes or leaving her smile around for people to find (much like Alice in Wonderland's Cheshire Cat).
