Golden Dash Mushroom

The Golden Dash Mushroom, commonly known simply as the Golden Mushroom and originally localized as the Super Mushroom is a more powerful counterpart to the Mushroom found primarily in the  Mario Kart series.

Mario Kart 64
In Mario Kart 64, the Super Mushroom appears simply as a yellow-capped mushroom, though its icon also shows a glow behind it. It gives the player an endless amount of speed boosts for a limited time. Compared to later games, it is fairly common, as it can be obtained from second to eighth place. However, it will generally only appear for someone in second place when the lead racer is significantly farther ahead.

Mario Kart: Double Dash!!
In Mario Kart: Double Dash!!, the Golden Mushroom is entirely gold and wears a crown decorated with red gems, which it keeps in all later appearances. Here, it is the Special item of Toad and Toadette, with Petey Piranha and King Boo also being able to use it. This makes it the only item that can only be used by unlockable characters.

Mario Kart Arcade GP
The Golden Mushroom makes an appearance in Mario Kart Arcade GP under the name Miracle Mushroom. It is one of Toad's special items, and it grants the user invincibility, as well as the ability to knock over any rival karts they run into, for five seconds. The Miracle Mushroom is functionally identical to the Star. A variant of the item known as the Miracle Mushroom+ exists. This variant extends the duration of the invincibility.

Mario Kart DS
In Mario Kart DS, the Super Mushroom takes its appearance from Mario Kart: Double Dash!! but can be used by any character. It can be obtained in 6th to 8th place.

Mario Kart Wii
In Mario Kart Wii, the Golden Mushroom's design is tweaked to follow the New Super Mario Bros.-inspired design the normal Mushroom is given. It can be obtained in 6th to 12th place.

Mario Kart 7
In Mario Kart 7, the Golden Mushroom can be obtained in 5th to 8th place. The European version of this game is the first time the name "Golden Dash Mushroom" is used.

Mario Kart 8
In Mario Kart 8, the Golden Mushroom has the same role as before. As with other items, its probability of appearing is now dependent on the racer's physical distance behind the frontrunner, with increasing likelihood the further behind they are.

Mario Party series
In Mario Party 10, Golden Mushrooms appear in the minigame Movin' Mushrooms, where they are worth three points. In Mario Party: Island Tour, Star Rush, The Top 100 and in Super Mario Party, the Golden Dash Mushroom is a usable item that lets the player add five spaces to their roll. In Mario Party: Star Rush, Golden Dash Mushrooms also appear in the Coin Chaos minigame, Conveyor Meltdown, where they must be sorted alongside normal Mushrooms.

Mario & Sonic at the Rio 2016 Olympic Games
Golden Dash Mushrooms appear as items in the 100m Plus event in the Nintendo 3DS version of Mario & Sonic at the Rio 2016 Olympic Games. In this event, the mushrooms grow and shrink continuously, and provide greater speed boosts when the larger mushrooms are collected.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, the Golden Dash Mushroom appears as an Ace-class support spirit, using its artwork from Mario Kart 8. When equipped, it makes the user temporarily giant at the start of battle. The spirit was originally only obtainable during the "Oh Yeah! Mario Time!" spirit event that ran from December 27, 2018 to January 1, 2019; as of version 2.0.0, it can be found at any time on the Spirit Board and Vault Shop.

To earn the spirit, the player has to defeat a gold Mii Brawler on the Figure-8 Circuit stage.

It's an awesome tool for those unfortunate enough to be in that position as they can use it to catch up to those in front.
