Tornado Jump (move)
From the Super Mario Wiki
The Tornado Jump is only used in Paper Mario and Paper Mario: The Thousand-Year Door. It is the last upgrade in Paper Mario. In order to use it, Mario must first find the Ultra Boots. It is found in Toad Town Tunnels in one of the deepest corners during the events of Paper Mario. It replaces Ground Pound as an upgraded version. It has the same effects as Ground Pound, except that it adds a higher second Jump; as such, it can be used to reach ? Blocks that are too high for Mario to hit with a regular Jump. In addition, there are sheets of ice in Shiver City and Shiver Mountain that can only be shattered with the Tornado Jump.
