This mario papercraft is the Golden Mushroom, this paper toy is designed by Sebastian Zych. The Golden Mushroom is an item that appears in several Mario games. It is a rare Mushroom with a crown on its head, and it always gives the player a positive effect when used. Golden Mushrooms sometimes vary by color and luster between games, but they are always a strong and rare item.
In relation to Mario Kart, a Mushroom is an item that gives the kart continuous bursts of speed over a time period of around eight seconds. A particular Mushroom known as the Golden Mushroom can also be used over and over. In tracks with lots of off-road areas, this item can be a lifesaver as it allows a racer to traverse terrain at full speed that would slow others down; creative racers can make effective psuedo-shortcuts. This can also be accomplished with a Star or a Mega Mushroom. Sometimes it is necessary to clear some optional jumps. Hitting another player during the boost allows players to steal any items in Mario Kart: Double Dash!!. If both characters have items, then the player will steal the rear character's item and have the front one drop their item. This is Toad's and Toadette's special item in Mario Kart: Double Dash!!. It also appears in Mario Kart 64, Mario Kart DS, and Mario Kart Wii.
