The new kid at school who gets all the attention because the kids all want to know what they're like and whether or not they'll be friends with him/her. Eventually, the "shiny new toy" factor wears off in about a week or two and the kid just becomes a normal student.
Kid #1: Hey, new kid! High five!
Kid #2: High five? Pshh, that's lame. Hey new kid, do I get a hug?
Kid #3: Me too! I want a hug first!
Kid #2: Back off, I saw the kid first!
Teacher: Kids, she is not a shiny new toy! Cut it out!
New kid: Umm...I think I'll just be going to homeroom now...
