From the Super Mario Wiki
The Double Cherry is an item first appearing in Super Mario 3D World. These cherries are found floating just above the ground or inside question blocks, they can also be found in crates.
When characters grab this item, a clone of themselves appears. The clones keep the original characters' state (for example, Fire Mario gets a clone), and moves identically to them. The clones can be used to activate certain switches and platforms. There can be up to five clones at one time. If players hit question blocks which contain Double Cherries when five doubles exist, a Coin will come out instead. The clones disintegrate if harmed, and they all disappear when the player grabs the Goal Pole and the player will be awarded with points. The players can also Ground Pound on other players to steal their double power.
Double Cherries also appear in Captain Toad: Treasure Tracker, acting just like they did in Super Mario 3D World.

- The Double Cherry is actually the result of a mistake made by a staff member with the placement tool, which created two player Marios. The staff thought it was a good idea, and decided to put it in the game.
- The Double Cherry is the only power-up in Super Mario 3D World where the character who picks it up actually speaks, rather than making a noise, as in the case of Cat Mario.
- In Mario Kart 8, a picture of the Double Cherry can be seen on 'Tropical Grocery' posters around the track of Toad Harbor and Toad's Turnpike.
