At the pause menu during the game press RB, LB, RT, LT at the same times and it will ask you to enable cheats.
Instead of using a cheat code to toggle "aging on" and "aging off" like in The Sims 2, you can de-activate the age in "Game Options" under "Options". When you uncheck the box next to "Aging", your Sims will no longer become older. You can also slow aging down in this menu by setting the "Lifetime" bar. It can be set from 25 days to 960 days.
Magic Lama Time
Click the start button and press LB, LT, RB, AND RT all together and click the top bar that says yes and then go to build and buy and go to decor miscellaneous and it's in the first box and voila!

When making a sim, go onto sskin and body, at the top of the page there should be a little skin coloured circle, click on it, choose the colour g1ren, red or blue, your sim will turn the colour you have selected, enjoy!
