Doom is a mouse nurse that works in a hospital called sparklecare Doom hates pretty much everything and everyone, and is very unhappy with himself and his life. He especially hates his job and his boss, his job does terrible things like torture patients and doom hates it... but life doesn't really go his way. Essentially nobody in the hospital actually likes him (except his sister mood) and the feeling is often mutual. He is very sensitive to most things and sometimes purrs in his sleep.
