Bomb Jump

From Wikitroid, the Metroid wiki

The Bomb Jump is a technique that can be done in Samus Aran's Morph Ball form. To complete this task, Samus must lay a Bomb, staying on top of it while still in Morph Ball form, and when it explodes Samus will be lifted in the air for a brief moment. Samus can do consecutive Bomb Jumps by placing Bombs at certain times, though this is very hard to do.

The method of doing this maneuver correctly is to place a bomb on the ground, then the moment it detonates, place another, and continue doing this until Samus reaches the place she is trying to get to. There are other variants of this technique, such as Double Bomb Jumping, Infinite Bomb Jumping, and Diagonal bomb jumping, the former being in Super Metroid, and the Prime games.

It should be noted that the technique mentioned above was taken out of Metroid Fusion, and then restored in Metroid Zero Mission.
