I'm starting a story classic horror characters reimagined as highschoolers often but not always gender swapped. I'm not looking for parts exsactly but if any one has ideas, link me to must have down loads or remind me of a monster I'm not thinking about. I'm talking ideas like anyone from the classic 1930s Universal Monster movies or anyone from the slasher genre or from shows like Ghostbusters, Gravity Falls etc. This is mostly brainstorming. looking for links outside of MTS or trying to think of key search words I may have overlooked. maybe just say your favorite characters and what stuff they need. Not looking for too many things as I don't want to fill up my memory.

Some vampire teeth:

@kaykeyser Gaybie posted some links to mersim cc in this thread. There is an orca fin too which is really awesome. I think someone posted a screenshot of their sim with it.
I actually made a siren attempt a while back with that CC, incase you needed some inspiration here are the pictures.

And if you'd like the link to the teeth she has they're here.

Edit: Here are some really unique and cool animal/monster/supernatural eyes as well!
If I find anything else, I'll let you know!
