Spring Jump (Paper Mario: The Thousand-Year Door)
It has been requested that this article be rewritten. Reason: the Mario vs. Donkey Kong and Paper Mario: The Thousand-Year Door jumps have only their names in common; i.e. they differ in everything else. For the Mario vs. Donkey Kong games, the article needs more details on exactly how the Spring Jump in later games "is different to the one in this game". (tagged on 20:04, 3 April 2016 (EDT))
The Spring Jump is a move used in Mario vs. Donkey Kong and Paper Mario: The Thousand-Year Door.
In Mario vs. Donkey Kong, the move is executed simply by jumping off a spring with timing. In the later games, though, the Spring Jump is different to the one in this game.
In Paper Mario: The Thousand-Year Door, it adds one more base damage to each jump (which now is 3 damage per jump). It is also the strongest upgrade in the game. To obtain it, Mario must solve the many puzzles in Riverside Station. It can be used as a field or battle move. On the field it is used to jump extremely high. If Mario hits a ceiling, he will fall to the ground a piece of paper and if there is an item on top, it will fall down. Mario can grab Pipes to reach previously unreachable areas. It is a useful Special Attack to use, especially against Smorg. It uses 4 FP and does 12 base damage. It is also the only way to get the Ultra Hammer. It uses the same Ultra Boots which in Paper Mario are used for the Tornado Jump, except that Mario retains his Spin Jump ability. The Stylish Move is performed by pressing 
at the highest point after the second hit. It does not award much extra Star Power.
Luigi's special high jump move in Super Paper Mario is identical to the spring jump from the previous games.
