Goo-Goo Buggy

The Goo-Goo Buggy is Baby Mario's signature kart in Mario Kart: Double Dash!!. It resembles a blue with a Smiley Flower emblem on each side. Its name comes from the onomatopoeia a baby makes.

Mario Kart: Double Dash!!
The Goo-Goo Buggy is a lightweight kart available when the game is first started. It has very low top speed, but very high acceleration and good handling. However, this kart is also rather light, and therefore is easily knocked around by heavier karts.

The Goo-Goo Buggy has the same speed and acceleration as the Toadette Kart in terms of stars, and the two karts are also tied in weight, meaning that they can't push each other around. However, the two karts are easily pushed around by the Para-Wing (another kart with the same in-game speed and acceleration, but is slightly heavier).

In terms of actual stats, the Goo-Goo Buggy is tied alongside the Toadette Kart and Para-Wing for having the lowest top speed, and the highest acceleration in the game.

Mario Kart Tour
The Goo-Goo Buggy will return in Mario Kart Tour starting from the 2022 Cat Tour alongside a new pink variant. It uses the Turbo Yoshi's tires. The Smiley Flower emblems have been replaced by the player's emblem.

Super Smash Bros. Ultimate
The Goo-Goo Buggy appears as an Advanced-class Attack-type spirit in Super Smash Bros. Ultimate, where it features the artwork of Baby Mario and Baby Luigi driving on it. It is unlocked as a reward for completing the challenge of KO-ing three characters in less than a minute in one match. When characters equip the spirit, it reduces their weight.

 * Website bio: "This souped-up baby carriage goes from zero to zoom in no time. However, once it gets going, it has a very low max speed. Plus, its light weight makes it a target for other karts to bully."

Trivia

 * In Battle Mode, the Goo-Goo Buggy's weight is tied with the Bullet Blaster's weight. However, it is heavier than the Bullet Blaster in any other game mode.
 * Similarly, the Toadette Kart in Battle Mode is heavier than the Goo-Goo Buggy, but both have the same weight in other game modes.
