Party favors for 5 year olds

I'm having a 5th birthday party for my daughter and her school friends are invited. It will be at a fun center with a huge play zone and roller skating. I dont really want to send the kids home with a bunch of candy and small trinkets that end up in the trash, what could be a good party favor? They will also each get tokens for games to win prizes at the party too and those prizes are often little things like you get in party favor bags.
