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 it does not propel Luigi up. Instead, the Scuttle slows Luigi's descent after he jumps. This allows him 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 subsequent reissues, Super Mario All-Stars and Super Mario Advance, Luigi jumps with a Scuttle, unlike Mario, Toad, and Peach.

Super Mario World: Super Mario Advance 2
In Super Mario World: Super Mario Advance 2, Luigi jumps as he did in Super Mario Bros. 2, instead of sharing Mario's jump properties as in the original version.

Super Mario Advance 4: Super Mario Bros. 3
While Luigi always kicks his legs when he jumps (unless he is holding an item) in Super Mario Advance 4: Super Mario Bros. 3, the gameplay effects of this move are available only when the Yellow Switch is active; it is always on in World-e.

Super Mario 64 DS
In Super Mario 64 DS, the Scuttle name is introduced, and the move is used with the same controls as Yoshi's Flutter Jump (done by holding in midair), and it can be used to reach the Mushroom Castle's roof before all 150 Power Stars are collected.

New Super Luigi U / New Super Mario Bros. U Deluxe
In New Super Luigi U, the Scuttle technique reappears, letting Luigi move horizontally at a higher altitude. In this game, Yellow Toad, Blue Toad, Nabbit, and Miis can also use this move. In the New Super Mario Bros. U Deluxe version of the game, Toadette can also use this move.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, Luigi kicks his legs during the entire jump (reminiscent of the move's appearance in Super Mario Bros. 2), as opposed to doing so only as he descends; this reduces his speed both upwards and downwards, making both halves of his jump easier to control.

Super Mario Maker
In Super Mario Maker, Weird Mario has a move similar to Luigi's Scuttle, extending his air time a little longer; however, it is used only briefly after he jumps and not while he falls.

Super Mario Run
Luigi retains his Scuttle to slow his descent in Super Mario Run.

Super Smash Bros. series
In Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate, 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 animation in Super Mario Galaxy and Super Mario Galaxy 2 is a reference to his Scuttle technique.
