Donut Block
Donut Lifts (also known as Donut Blocks) 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 Mario or Luigi 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 Lifts.
Super Mario World 2: Yoshi's Island and its remake Super Mario Advance 3: Yoshi's Island, as well as the sequel Yoshi's Island DS, also contained Donut Lifts. Super Mario RPG: Legend of the Seven Stars additionally featured them, accurately adapting their platforming concept into its isometric field gameplay. They also appear in Super Princess Peach, New Super Mario Bros., Mario vs. Donkey Kong 2: March of the Minis, and New Super Mario Bros. Wii where they do the same thing. In the latter, some longer platforms with the same coloration and effects as donut lifts also appear. Super Princess Peach in particular also had blue versions, that, if stood on, drop almost immediately, so fast that Peach needed to use Gloom to make it over.
Donut Lift-like platforms appear in Super Mario 64 and its remake, Super Mario 64 DS; these possible Donut Lifts resemble their two-dimensional counterparts, but are shown to be rather long (whereas Super Mario RPG previously showed confirmed "three-dimensional" Donut Lifts to more square-shaped than rectangular). In Hazy Maze Cave there are lifts to help the player get Elevate for 8 Red Coins and Underground Switch Star (In Underground Switch Star, you don't need to use the Donut Lifts). In Lethal Lava Land's volcano, they appear near the top, along with the moving platforms. In Rainbow Ride, most had to be jumped over during the magic carpet ride and some served as bridges to other parts of the level. Long Donut Lifts of this style are also seen in Mario & Luigi: Superstar Saga, but only in Guffawha Ruins. In Mario & Luigi: Bowser's Inside Story they appeared once, but only in a cutscene.
