So basically if you get a pack that comes with a world, you can get launched into that movies setting (for example: if you get the starter pack it comes with Sulley, and you can play on the Monster's University campus). Once you start playing, characters from the movie wander around and ask for your help with quests and such. Some figures don't have their own world though, so you can play with them in the "Toy Box", which is basically just a free play where you can decorate it how you want and do your own thing.

I was so excited to get it but I didn't it because I forgot about it and if I forget about it why should I get it :P (not saying I don't like DI) they should if they didnt add frozen; Olaf!
Olaf would be such a cute character! I would definitely buy that!
