Instructions
Tap and hold the Nintendo DS stylus on the item that you want to delete or move. Once your tap and hold an item, the recycle bin will appear in the upper-right corner of the game screen.
Drag the item to the recycle bin or anywhere on the game screen.
Release the item. If you release the item over the recycle bin, it will be deleted. If you release the item anywhere else, it will be placed at that location. Upon releasing the item, the recycle bin will disappear, and will only reappear once you select another item.
