Scuttle

The Scuttle is a move mainly used by Luigi in several games in the Super Mario series. It is similar to Yoshi's Flutter Jump, except that it does not propel Luigi up. Instead, Scuttle will slow Luigi's descent after jumping. This will allow Luigi to reach greater horizontal distances and allows the player to easily control the landing. The animation for the technique is Luigi kicking his feet in the air, which is also similar to Mario or Luigi's fall under the influence of a Mini Mushroom.

Super Mario Bros. 2
In Super Mario Bros. 2 and its remakes, Luigi and Princess Peach can use this move to jump farther.

Super Mario World: Super Mario Advance 2
In Super Mario World: Super Mario Advance 2, this move appears, behaving exactly like it did in Super Mario Bros. 2.

Super Mario Advance 4: Super Mario Bros. 3
This move returns in Super Mario Advance 4: Super Mario Bros. 3 and is possible when the Yellow Switch is active.

Super Mario 64
In Super Mario 64 DS, this move can be used to reach the castle roof before all 150 Power Stars are collected.

New Super Luigi U
In New Super Luigi U, the Scuttle technique reappears, enabling him to move horizontally at a higher altitude. In this game, Yellow Toad, Blue Toad, Nabbit, and Miis can also use this move

Super Mario 3D World
In Super Mario 3D World, Luigi kicks his legs during the entire jump, as opposed to kicking them as he descends (reminiscent of its appearance in Super Mario Bros. 2); this reduces his speed both upwards and downwards, making both halves of his jump easier to control.

Super Smash Bros. for Nintendo 3DS / Wii U
In Super Smash Bros. for Nintendo 3DS / Wii U, Luigi's jumps use a Scuttling animation, as opposed to his jumps in previous games in the Super Smash Bros. series, where they were similar to Mario's.

Trivia

 * Luigi's Triple Jump in Super Mario Galaxy and Super Mario Galaxy 2 is a reference to his Scuttle technique.
