Sometimes you have many different items on the ground and it would be nice to be able to pick up everything at once (maybe within a certain distance). My thought was that a rake could be a new tool to do this.
A bulldozer would be cool, too. It would be used for moving everything from one end of the street to another. So, you could use it in your house after a messy party. Certainly not needed, but worthy of a few snaps, and totally amusing!
