On Sims 2 Ds The Rat Cave is in the Basement in the Large Blue and Grey Doors by the Freezer. The doors look like lockers (hidden) and will open automatically if you walk up to them.
. You have to buy Rat Cave . wear rat suit . find Jimmy and friends .sneak up behind him and while the light is flashing press it
if its sims 2 on ds you just need a water gun cuz the aliens hate water in that game. They Are Also Scared Of Rats So if you get the rat cave you can change into a rat and they run away. But You will hardly ever see the aliens unless you change the time on your DS and then change it back the receptionist will call you a sneaky Time traveler or something like that and aliens will hang aroung for 3 Days unless you get rid of them by making them run away with the rat suit of soak them with water i should now I've done it!
You don't. You can't do this in any of the DS Sims games.
On the second Island just past the cave there is a chasm there to.
You have to get the Sims 2 game boy advance game and have them both in your DS at the same time. Then you can have babys.
you need to obtain the rat suit from the rat cave located behind the lockers in the hallway where the freezer is located...once you get the suit click on the rat face where your cell phone usually is...the question mark will tell you what each icon means. good luck!
