Uproots are enemies from Super Mario Odyssey that can be controlled with Cappy. In their natural state, Uproots have flower pots on their heads, and have red eyes. They are shown to resemble onions when their flower pots are knocked off. They can stretch their legs, which, according to the Bonneter biologist, telescope outward, to reach high places.
Uproots can be found in the Wooded Kingdom, a secret, lava-filled area in the Seaside Kingdom, and the Darker Side. In order to break the flower pots on their heads, Mario needs to throw Cappy at them, allowing him to take control of the Uproot. They can be used to reach places Mario normally could not reach as well as raising certain platforms. They are also needed to defeat the boss Torkdrift through smashing both blocks and the boss's core.
A concept design for the Uproot depicted them as mushroom type enemies.[1]
In the Super Mario Mash-Up Pack in Minecraft, Striders are replaced by Uproots.
