The green clouds on the floor indicate that something is on the floor that has... spoiled. Try getting a sim to clean it up.
Click the floor towards where you want to go.
You have to go to the build section and buy stairs and then you have to make a floor.
Unless there is a mod to change this, you cannot make your sim just sit on the floor. The "Hang Out" option will sit them on the floor but that is two sims "hanging out" and talking on the floor...they do not just idly sit there.
Tap on the floor and click go here!
there are no alien abductions in sims 3 yet. or you can change colour of your sims skin and make it blue green red or normal then you could think of them as aliens
The sims 3 for ds is much diffrent to the pc one i have it for ds lite i dont now about 3ds (on the sims 3 for ds you cant have a baby or o 2 floor house)
L1 and down button.!! Sorry if I answered this late!!
no, the closest thing to aliens in the sims 3 is making your sims green or any other color.
When your in the build mode, just click on the floor boutton in the bottom left with the up arrow.
In the genral store on the 2ed floor of the market
You can turn the green on the skin chooser, and make them really distorted, but at the moment we can't really have zombies, but there are ghosts on the sims 3
on create-a-sim chose the button with people's silhouettes next to your Sim's picture and look for the Sims that have the green diamonds next to them
