New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Leaf Platforms first appear in New Super Mario Bros. U and New Super Luigi U as platforms that appear on giant beanstalks. When they first sprout, they appear to be green, only to turn brown and slowly float down. Leaf Platforms appear in Skyward Stalk in the former game and in Beanstalk Jungle in the latter game.
Leaf Platforms reprise the aforementioned roles in New Super Mario Bros. U Deluxe.
Donkey Kong Country: Tropical Freeze
Rolling leaves also appear in Donkey Kong Country: Tropical Freeze in the level Horn Top Hop, where they appear orange and travel on their intended path until they reach the end of the path, where they turn brown and eventually disintegrate. Some rolling leaves may also be floating indefinitely from gusts produced by alphorns.
Yoshi's New Island
Several leaf platforms also appear in Yoshi's New Island in the level Bouncy Beanstalk Walk. If the player stands on them for too long, they will eventually fall off. A few leaf platforms also appear in Big Beanie's Castle, exclusively in the area leading to the battle with Big Beanie.
