A few minutes ago she'd been flesh and blood (and covered in fur) same as you. But then you did the one thing you knew you shouldn't do around Jazz, and that was bring up talk of things that melt. This time it was about the ice-cream you wanted to get. That's all it would take for jazz to start melting.
She loved to melt, was obsessed with it, and now she sat there happily melting in the bowl urging you to eat her. You cast an unlimited capacity spell on your stomach, the same you would to make a bag of holding.
"So you can still feel this?" You asked.
"Yes."
"So what part of you am I eating now?"
"I'm not going to tell you, but you can guess from my facial expressions if you like."
You put the spoon into you mouth. It was icy-cold, soft, and creamy. She was definitely turning into ice-cream.
Jazz began to giggle, and wriggle a little in the bowl.
"Your toes?" You said after you swallowed.
"Mhm." she affirmed.
With the next spoon full she giggled a little but also blushed. Something you wouldn't have otherwise seen if she'd have still had fur.
"Was that?....
"Yeah." she said, and immediately began to melt even quicker.
She straightened her rapidly melting legs and thrust her hips up in order to sink her upper half into the already liquid cream. She let out a soft, relaxed "Mmmm..." which turned into a gargle of bubbles as her head sunk below.
As you ate, you thought that would be the last you'd see from her for the remainder of the day, but when all of the remaining solids had melted, and you were left with just the last little bit of cream, you felt your spoon hit something soft but still solid underneath.
You titled the bowl and the cream pooled to one side, revealing the flattened face of Jazz yet to melt. She slowly opened her eyes and before closing them again, her lips turned into a gentle smile that stayed there until she had finally melted.

This is Jazz, she's a raccoon, and she likes to melt. She wasn't always able to do that, but one day whilst looting, she encountered a protective spell designed to tempt looters into taking something else more desirable. For Jazz that happened to be melting... I think she took it.
