New Items

There are many new items that you can in Super Mario 3D World such as the Koopa Shell, Light Box, Cannon Box and a few others.
I really liked all of the items, however It would have been cool if the Light Box could kill the Dry Bones since they're undead like the Boos.

I like them all.
I just wish I could find a Lucky Bell...

^ Wouldn't that be a power-up? Nintendo counts the boxes as a different thing than the suits/power-ups you can get in the other games it seems, which somewhat makes sense.

Anyway, they're cool, I personally would prefer seeing some more interesting power-ups rather than the boxes though.
