Would your sona(s) rather be deaf or blind?
Rabid would rather be blind, his hearing is the primary sense he uses.
Mushroom would rather be deaf, he needs to be able to see where he's going.
Osiris could be either, he has sensors in his tail that help him identify his surroundings (I've never gone into how long his tail is, it's about as long as his body).
Anubis could easier be blind than deaf, his ears are huge so he can hear easier.
Vodka couldn't go easily without either...but dust to dust, he'd rather be blind.
(Rabid can't walk worth anything, morning or afternoon. We both have bad balance.)
