Kids characters

[shupe]

I'm doing an activity with our 1st through 5th graders at church on Wed night, where you pin the name of someone famous on their backs so they can't see and then they can ask other kids yes/no questions to figure out who they are. They aren't going to be Bible related. I need at least 20 names and I'm having a hard time coming up with some that I'm pretty sure most of them will know. I have my own 3rd & 5th grade experts, but I can't ask them because they'll be playing! I'm also trying to make sure that I have both boy and girl names. Here are my ideas so far.:
Hannah Montana
Superman
Batman
Luke Skywalker
Santa Claus
Cinderella
Christopher Columbus
Little Red Riding Hood
Fairy Godmother
Tinkerbell
Charlie Brown
Strawberry Shortcake
Pocahontas
Wonder Woman
Ramona Quimby

Thanks!!
