I became underfell papyruses kitten!?

dream, ink, and the rest of the multiverse have taken everything from nightmare his family his friends everything. they killed error his best friend they killed his adoptive children everyone he ever cared about. so imagine his surprise to waking up in a kittens body in underfell after trying to kill himself? and not only that he's underfell papyruses cat!? what has the multiverse become or is he even in the same multiverse? why is there only one universe in this multiverse and why is it an underfell universe instead of a classic one? he has so many questions but he traded it all to live the life of an ordinary house cat that seems to be more of a guard dog than anything.
