Flimsy Lift

Flimsy Lifts are a type of lift found throughout the 2D games in the Super Mario series. They fall once the player steps on them.

Super Mario Bros.
Flimsy Lifts debut in Super Mario Bros. They are lifts that drop when the player stands on them, only to stop falling once the player gets off of them. Only seven appear in the entire game: one in the middle of World 3-3, four near the end of World 6-3, and two at the beginning of World 7-4.

Super Mario Bros.: The Lost Levels
Flimsy Lifts return in Super Mario Bros.: The Lost Levels, behaving exactly the same as in Super Mario Bros. This time, they first appear as early as World 1-2, and appear in every world thereafter, with the exception of Worlds 2 and 9.

Super Mario Bros. 3 / Super Mario Advance 4: Super Mario Bros. 3
Flimsy Lifts return in Super Mario Bros. 3, appearing only in World 1-4. They behave mostly the same as the predecessors, except that they now move horizontally, and no longer stop moving when the player steps off of them.

Flimsy Lifts behaving like their Super Mario Bros. counterparts also appear in Super Mario Advance 4: Super Mario Bros. 3's World-e level Caped Escape.

Super Mario World / Super Mario World: Super Mario Advance 2
Flimsy Lifts return in Super Mario World, behaving as they did in Super Mario Bros. 3, though they now initially remain stationary. They mainly appear in secret areas of Donut Secret 2 and Chocolate Secret as well as throughout Star World 5, though two also appear in Butter Bridge 1, one appears in Chocolate Island 4, and three appear in Way Cool.

Super Mario Land 2: 6 Golden Coins
Flimsy Lifts return in Super Mario Land 2: 6 Golden Coins, behaving as they did in Super Mario World. They appear in the Tree Zone and Macro Zone and look the same as regular lifts.

New Super Mario Bros.
In New Super Mario Bros., only two Flimsy Lifts appear in the entire game, specifically at the end of World 6-5. They behave the same as in Super Mario World and look the same as regular lifts.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Flimsy Lifts appear as placeable course elements in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2, behaving as they did in Super Mario World and New Super Mario Bros., though they are now given a bluish hue to properly differentiate them from regular Lifts. Placing wings on a Flimsy Lift makes it fall more slowly, and placing one on a track makes it act like a Rail Lift that remains stationary until the player lands on it.

Yoshi's Island DS
In Yoshi's Island DS, a total of seven Flimsy Lifts appear in the final segment of the level Superhard Acrobatics!. They behave the same as in Super Mario World.

Unused appearances
While Flimsy Lifts do not appear in New Super Mario Bros. Wii, New Super Mario Bros. 2, New Super Mario Bros. U, or New Super Luigi U, they nonetheless appear in the games' files, implying that they were meant to appear in each game.
