Multi-Vator

Multi-Vators are a type of platform that appears in Super Mario 3D World and its campaign in Super Mario 3D World + Bowser's Fury, as well as Captain Toad: Treasure Tracker and its ports. Multi-Vators have a number printed on them that indicates the minimum number of characters that must be standing on the platform in order for it to move, which generally allows access to a hidden secret. They generally appear in stages with Double Cherries, so that a player can use clones to meet their requirements by obtaining Double Cherries. In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, Multi-Vators may be activated by multiple players, one player using multiple clones, or any combination of players and clones that is equal to or greater than the number on the Multi-Vator.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, the first Multi-Vator appears at the end of Double Cherry Pass, and requires four characters to ride it to the level's third Green Star. Another four-character Multi-Vator appears next to the Checkpoint Flag in Beep Block Skyway, leading to the level's Stamp. Three Multi-Vators appear in Backstreet Bustle: the two-character one sends the player from the beginning to the area in the middle, the three-character one leads the player to the third Green Star, and the four-character one leads the player to the second Green Star. A two-character Multi-Vator appears near the end of Cakewalk Flip, and leads to the level's Stamp. A two-character Multi-Vator also appears close to the end of Rolling Ride Run, taking the player to the third Green Star.

Captain Toad: Treasure Tracker
In Captain Toad: Treasure Tracker, a single two-character Multi-Vator appears in Double Cherry Spires, where it is used to obtain the Power Star. Multi-Vators are also present throughout Multi-Vator Mayhem, and are primarily used to progress throughout the level. Said Multi-Vators reprise their role in Boo Spotting at Multi-Vator Mayhem.
