What are some fun things to do at a sleepover?

Well, I turn 12 on Monday, not really having a big party this year, but I still want it to be good, so I'm having a sleepover. I'm having two sleepovers one with 2 friends from primary school, and one with 2 friends from secondry, I'd have it all together but they dont really get along. So, we'll be sleeping downstairs on a blowbed, that means we'll get the virgin plus box with music and kids channels and everything, so that should be good, and were having like buffet food for tea. We might play on sims for abit too. Also we have this friendship book so we might do that but that bores us after a while.my house is not really anything special, so I don't no what to do? Any suggestions, were into funny things and girly things? also my mum said she'll buy me a film for us to watch, any suggestions on funny or scary or girly films? Thanks.
