In order to get Moogoo Monkey for the casino a player would need to play The Sims 2 (Nintendo DS) with The Sims 2 (Game Boy Advance) in the GBA slot. This is unavailable in the Nintendo DSi, DSi XL, 3DS and the 3DS XL because it does not have a GBA slot but instead you can play Moogoo Monkey on wireless until you get is you will be informed. It is possible to unlock Moogoo Monkey in The Sims 2 by using a DS or DS Lite and then playing it on a DSi/DSi XL/3DS and 3DS XL after the game is unlocked.
Another way to get Moogoo Monkey for the casino is to play the game on December 14th.
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!
Each NPC has a secret that they will only share wil you're sim when they fully trust them and are 'bestfriends'
Secret outfits can be unlocked when you're sim vistits the start pannel when they have completed the game
