The kart itself seems to be similar to the Egg 1 as they both are a character's trademark as a kart itself. The kart appears to slightly resemble a Mushroom Car and is shaped like a mushroom with small wheels. Has low speed, weight and item usage, and high acceleration, handling, and drifting.
The Mushmellow returns in Mario Kart Tour, as a Normal kart. It appears to use the same tires as the Pipe Frame. The game also adds in two new variants of the Mushmellow, one of which being the Pink Mushmellow, which uses designs based of Toadette and is also classified as a Normal kart, and the Cheermellow, which was part of the Winter Tour as a High-End kart.
- The kart's name is a portmanteau of the words "mushroom" and "marshmellow".
