Donut Block

Donut Blocks (also known as Donut Lifts, Falling Blocks  or donut platforms ) are a kind of platform first appearing in Super Mario Bros. 3. They get their name from the fact that they are round (except for the top) with a hole in the middle. If the player stands on one for more than a second, it drops below. For this reason, Mario and Luigi should avoid touching the ground by jumping as much as possible when crossing Donut Blocks.

Super Mario Bros. 3
Donut Lifts debut in Super Mario Bros. 3. They shake when Mario stands on them and fall soon afterwards. In Super Mario Advance 4: Super Mario Bros. 3, there are spiky variants only seen in Bowser's Last Stand.

Super Mario Land
In Super Mario Land, unnamed Donut Lifts appear in many levels. While fundamentally the same, this version of the Donut Lift falls with little warning, and often Mario must run across them.

Super Mario 64 / Super Mario 64 DS
Donut Blocks appear in Super Mario 64 and its remake, Super Mario 64 DS. These platforms resemble their two-dimensional counterparts, but are shown to be rather long (whereas Super Mario RPG previously showed confirmed "three-dimensional" Donut Blocks to be more square-shaped than rectangular). In Rainbow Ride, most have to be jumped over during the magic carpet ride and some serve as bridges to other parts of the level.

New Super Mario Bros.
Donut Blocks reappear in New Super Mario Bros. In this game, they turn red before falling. Once they fall, they never regenerate.

New Super Mario Bros. Wii
Donut Blocks reappear in New Super Mario Bros. Wii, where they function the same as in New Super Mario Bros.. There are also yellow bars with grooves on their ends. When Mario walks over or hangs on them, they behave the same as Donut Blocks, turning red for a second before falling down. This variety appears only in World 4-2. Donut Blocks also appear during the boss battle in World 5-Castle.

Super Mario 3D Land
Donut Blocks reappear in Super Mario 3D Land. However, in this game, when being stomped on, they immediately fall down slowly and disappear below the stage. A rock variation exists, and it has the same effect.

New Super Mario Bros. 2
The Donut Blocks make an appearance in New Super Mario Bros. 2. Glacial versions of the Donut Blocks also appear in the snow world (World 4). These Donut Blocks are slippery and can be differentiated from the ordinary Donut Blocks by their light blue color. Other than being light blue and slippery, they share every characteristic of the normal Donut Blocks.

New Super Mario Bros. U
Donut Blocks also appear in New Super Mario Bros. U with the same functions as in the other games. Magikoopa also uses them in his battle by firing spells at the solid floor Mario can stand on. These Donut Blocks can be triggered by Mario in any form, even as Mini Mario. This same behavior reappears in New Super Luigi U and New Super Mario Bros. U Deluxe.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Donut Blocks appear in Super Mario 3D World and its port with the same design and behavior from Super Mario 3D Land. They now turn red when stepped on.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Donut Blocks reappear in Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2, with the same functions as in the other games. In the Super Mario 3D World style, Donut Blocks are completely solid and cannot be jumped through, as well as taking on a more square appearance than the original game the style is based on. Thwomps can trigger Donut Blocks.

Yoshi's Island series
Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3, as well as the sequels Yoshi's Island DS and Yoshi's New Island, also contained Donut Blocks. In Yoshi's New Island, a variation that is four times the normal size appears.

Super Mario RPG: Legend of the Seven Stars
Super Mario RPG: Legend of the Seven Stars additionally features them, accurately adapting their platforming concept into its isometric field gameplay.

Super Smash Bros. Melee
Donut Blocks appear in Super Smash Bros. Melee, in the stage Rainbow Cruise.

Super Smash Bros. Brawl
Donut Blocks reappear in Super Smash Bros. Brawl, in the returning Rainbow Cruise stage. Also, Drop Blocks, blocks with a down-pointing triangle on them, act just like Donut Blocks. These blocks are only used in the Stage Builder and certain stages of The Subspace Emissary.

Super Smash Bros. for Nintendo 3DS / Wii U / Super Smash Bros. Ultimate
Donut Blocks also appear in the 3D Land stage in Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate. They also appear in the downloadable Super Mario Maker stage.

Mario & Luigi series
In Mario & Luigi: Superstar Saga and Mario & Luigi: Superstar Saga + Bowser's Minions, a few Donut Blocks can be found in Guffawha Ruins. In Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, Donut Blocks only appear in the Flab Zone, which are suspended over in the mucus. Luigi steps on these blocks, and they fall down into the mucus, causing him to fall into it as well, where he is rescued by Princess Lipid. Mario & Luigi: Dream Team, Donut Blocks appear in area B of Dreamy Neo Bowser Castle. They retain their colors from the New Super Mario Bros. games, but are much thinner, more stretched and rounder this time around. They function similarly to Super Mario 3D Land, where, once they are stepped on, they turn red and fall after a short time.

Mario vs. Donkey Kong 2: March of the Minis
Donut Blocks reappear in Mario vs. Donkey Kong 2: March of the Minis, where they function the same as in previous games.

Super Princess Peach
Donut Blocks reappear in Super Princess Peach, where they also have blue variants. If Peach stands on these blue Donut Blocks, they will fall immediately, so Peach needs to use her Gloom Vibe to quickly move across them.

Mario & Sonic at the Sochi 2014 Olympic Winter Games
Donut Blocks make a small appearance in Mario's Figure Skating Spectacular in Mario & Sonic at the Sochi 2014 Olympic Winter Games, where they retain their design and function from Super Mario 3D Land.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
In Yoshi's Woolly World and Poochy & Yoshi's Woolly World, Donut Blocks appear, retaining their function from the Yoshi's Island series. In this game, they appear to be made of sand, and disintegrate and fall when stepped on. Unlike previous installments, they do not turn red when falling.

 * 3DS Virtual Console Manual Bio: "More of a drop than a lift. When you step on this, it will shake and drop."
