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...

The feeling you get in a long term relationship when you develop a crush on someone else for a short period of time.
I love James and i'd never leave him, but i think i have a slight crush on Will! Ugh i must have shiny new toy syndrome, it'll pass in a week!

He/she might have been the new toy speaking the new language, had lazers on his/her head and could fly, Andy might have even loved the new toy more than his original toys, but they knew deep down that they loved Andy more.
