My mom has hosted one of those "toy" parties before. For snacks she had the naughty shaped molds, so she made some jell-o jigglers in those shapes. She also melted chocolate and made naughty shaped chocolates. You can also make naughty shaped ice cubes for drinks...LOL
She also has the naughty muffin tins.... I sometimes bring those in for co-worker's b-days...LOL

At my co-worker's bachelorette party there was a game like the one kt_luvs_kitties suggested.... only instead of a banana it was a pair of lips (made out of paper). Each guest was blind folded, spun around a couple times and then holding the lips with their mouth they proceeded to try and place the lips in the "best" spot on a poster of a mostly naked guy. Then there were prizes for most conservative kiss, and hottest kiss...etc.... (I won hottest kiss btw....) It was a lot of fun and should be fairly cheap for you to do at home.

I hope some of these helped. Have fun!
