Hello! Come and introduce yourself!

Hi everyone, very new obviously, haha. I'm honestly just here because I'm desperately looking for the answer to one question: can you get a sim with human skin and alien eyes? I'm a writer and streamer and I need to make a particular looking sim for a storyline my subs want me to do. I love playing the sim in general, and my favorite part of it is the character creator. I don't have a lot of packs, but there are a lot of cool ones I hope to get, like the vampire pack and the island one (I want mermaids! haha). Designing houses is tons of fun. I've maxed out my favorite sims in their careers and aspirations so now for me it's just about being creative and trying new careers and challenges. I hope that being here will help me get more ideas. Thanks!
