How Do i get new effects in Photobooth (like dizzy, lovestruck, nose twirl, etc)

Hello.

I have a 13 inch MacBookPro that I purchased in December, 2010. It's an OS X.

I went to the Apple Store yesterday and I was fiddling with the other MacBookPro's there, and I was on Photobooth. I noticed that there are some new effects like "Dizzy", "Lovestruck", "Nose Twirl", "Chipmunk", etc. I approached the Apple store man, and told him that I hadn't updated my Mac for a while, and was wondering that if I updated my Mac, would I get those new effects. He said yes, so I went home and updated my MacBookPro, but I still haven't gotten those new effects.

Could somebody please help me?

Thank you.
