GameSpot has posted a new gameplay movie of the GBA version of the URBZ a few days ago. In 2 minutes you're taken through several parts of the gameplay. Some mini games are shown, as well as creating your urb and some other parts of the game. Not all of it is new, as some snippets have already appeared in previous clips. You need a free GameSpot Basic account to be able to download it. You can get it from the media page.
