Double-Decker

The Double-Decker is a High-End kart in Mario Kart Tour. It was introduced in the London Tour and is the signature kart of Waluigi (Bus Driver) and Rosalina. The kart resembles a, like its name indicates, and has a plaid-patterned seat similar to that of the Swift Jack. It also has the Mario Kart logo on the sides and on the destination display signs. The emblem is located on the grille, sides, and rear. It uses the Standard tires from Mario Kart 8 and Mario Kart 8 Deluxe; however, the original icon before Version 1.4.1 showed it with the Pipe Frame's tires. The Double-Decker increases the duration of speed boosts resulted from Dash Panels and the points earned for driving over Dash Panels. A dark green variant called the Green Double-Decker was introduced in the September 2021 Sydney Tour, and a golden variant called the Gold Double-Decker was introduced in the Anniversary Tour.
