Toad Circuit is the first course in Mario Kart 7, as well as the Mushroom Cup. It replaces the Luigi Circuit. It is the 1st track of the Mushroom Cup. there are three Toad balloons on this track, floating around and onto some string. There are two bridges: one small white one and big yellow one. Yellow tunnel-like bridge highly resembles one of the bridge in Figure-8 Circuit in Mario Kart DS. It highly resembles Wii version of Luigi Circuit, but with Luigi's green cap has taken away. Also, Toad balloons replace Luigi's single balloon.
This course highly resembles Luigi Circuit. In fact, it had exactly same shape, although many things there look different, such as Luigi's things has completely taken away. It also uses different music. Strangely, Luigi's yellow garage still exists, although many people think it belongs to Toad, especially if they had never seen Luigi Circuits in Mario Kart: Double Dash‼ or Mario Kart Wii. Same as Luigi Circuit, but you have to opposite direction. Three Toad balloons: red, yellow and blue. Gliding pad is added to the course along with two new bridges and single tunnel. Luigi's cap no longer exists and his balloon must be popped if three Toad balloons are added in this course.
