Wackiest Occult Sims...

Honestly, I wouldn't mind the return of imaginary friends.

We've already had plumbots / simbots, and we've already had pets, but never pet llamas... how about upping the ante and introducing both llamas AND robollamas?

Golem / Elemental sims would be unexpected but awesome, especially with powers corresponding to their elements

Giant sims! I have NO CLUE how this would work gameplay-wise, but imagine a new world that's just a village of (mostly) friendly giants, maybe past a beanstalk in the sky, where you can send your other sims and have them try different ways of communicating with the giants! It could come in a fairy-tale themed pack with magic beans and talking animals and other fairy-tale staples, maybe even dragons! I'm getting ahead of myself but, imagine! :D
