It is possible to unlock Moogoo Monkey in The Sims 2 by using as DS or DS Lite and then playing it on a DSi/DSi XL/3DS and the 3DS XL after the game is unlocked.
 * When you unlock the Bovine Shrine, there will be three other sims worshiping The Prime Heifer with Ava Cadavra. These sims are Ara Fusilli, Auda Sherif, and Sancho Paco Panza. You can not interact with these sims as they are in a trance, but have you ever wondered what they have to say? Just distract them by spraying them with the water gun which can be found in your sim's inventory. This will make them angry, and you will then have the option to either calm them down or ask What's Up? This will not help you to advance in the game per se, but it is worth trying as they say some hillarious things!
