I thought it was the giraffes that have long tongues.
They do but a Giraffe also has a blue tongue.
But there aren't even any openings in people's eyes! How is that possible?
Well... Actually there can be. I think it is a Macular Hole or something, I don't know if everyone has it because it sounds like a Condition or something.
On the topic of where my Sims vomit from, it depends on the sim, I personally think it must be how they have been brought up, some throw up their whole face, others just their mouths.
