New toy 

The shiny, fresh one that just came out the box with no dust on it.

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.

shiny new toy 

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...
