just had the idea of xisuma teaching c!slimecicle how to become bones
they meet somehow and charlie tells xisuma that "hes bones and definitely not a slime"
to which xisuma plays along and then whispers "do you want to know how to actually become bones"
charlie then still says hes bones and a human but "is just curious"
this begins xisuma becoming c!charlies bone dealer, and charlie literally becoming bones
