Vampires:
Expansion Pack Needed: Nightlife
To do: go around the downtown area until you meet a count or a countess. They are vampires of course, and they look like classic vampires. Befriend one, and when you get a high enough relationship, they will bite you, and turn you into one. Beware, though, as they are no longer normal sims.
Plantsims:
Expansion pack needed: Seasons
To do: have a sim get a gold talent badge for gardening. Then, when the trees need spraying with pesticides do so. If you do it enough, you sims will turn plant.

Yes

Vampires, werewolves, plant Sim's, witches, warlocks, zombies, ghosts. I think that's it.
the cow plant is only in the sims 2, you can not get one in the sims 3
