Some suggestions for mall scavenger hunt?

Well my friends and I are going to the mall in two days and we are gonna do a mall scavenger hunt. ( My idea) and I am the one who is going to make the list. Can you please help by suggesting a few things i should put on there? The things we look for should be somewhat uncommon to see and can be items or people. (For example, like a little girl in pig tails eating a pretzal or a furry eskimo jacket)
