animated movie title?

[TOtallyCLuless]

idk if its out yet but i saw a preview when i was out of states and it looked interesting. its an animated movie about a boy who has a crush (i think) on a girl and her wish is to see a real live tree so he goes in search for one. it looks like something straight out of dr. seuss as far as the bright colors are concerned. if anyone can tell me what the title of the movie is i'd appreciate it a lot thanks
