Remove his mouth all together but keep his eyes, now he's just pure meat with eyes that stare at you wherever you go, stalker type shit.

"A mouse who's face was so iconic that once brought joy and laughter with a smile wherever it went, but now a skewered rat with it's once kind heart and soul, ripped out that serves as a vessel with abnormal intentions, words are silent as the wind but the actions it makes are loud and clear, it's fallowed by spirits of the past that never lets go of what it's done, the stopping point is never known of this creature and will continue to wonder until it finds the source of what it wants most, peace and rest.

(sorry, forgot the community's lmao)
