Baby Park is a race course belonging to Baby Mario and Baby Luigi that has appeared in Mario Kart: Double Dash!!, Mario Kart DS, and was added to Mario Kart 8 as part of the Animal Crossing × Mario Kart 8 DLC Pack. Being a simple oval loop with no hazards, it is the shortest course in length in the series, excluding the unused "Test Circle" course found in Mario Kart DS and Donkey Kong Jungle from Mario Kart Arcade GP, only taking around ten seconds to complete a whole lap. As the name implies, the course takes place in an amusement park, including various elements from the Yoshi franchise. The track is a platform hanging from a large support complex, where a roller-coaster runs above and around the course and a pink train runs over the rails. It is possible to collide with the roller coaster, though it is very difficult to achieve. The roller-coaster obstacle was removed in the DS version and it returned in the Wii U version of the track.
The file names for this course in Mario Kart: Double Dash!!, including ghost data, have "BabyLuigi" as a prefix or suffix.
Mario Kart: Double Dash!!
Baby Park is the third course in the Mushroom Cup. One half of the floor is blue and the other half is pink. It has various pictures of characters from the Yoshi's Island series on it, including Baby Mario and Baby Luigi. Due to its length, this course has seven laps instead of the traditional three, making it one of only two courses in Mario Kart: Double Dash!! to not be a three-lap course; the other course is Wario Colosseum, which has two laps. DK Mountain can be seen in the background.
Baby Park's music was also used in Balloon Battle on Tilt-a-Kart, though with more cymbals and the opening notes is cover version of the Super Mario Bros. theme rather than the beginning notes of the Baby Park piece.
Mario Kart DS
Baby Park appears in Mario Kart DS as the last track in the Banana Cup. This time around, it has five laps instead of seven. Missions 2-8 and 3-Boss take place here. It was available in Wi-Fi. On the final lap, the music starts playing in G♭ Major instead of A Major.
Mario Kart 8
Baby Park reappears in Mario Kart 8 as a heavily-revamped DLC retro course and the first track of the Crossing Cup. This is the only retro track in the Animal Crossing × Mario Kart 8 DLC pack that has already appeared at least once as a retro track. One of the major changes made to the race course is that the entire track is now slanted, making it entirely an anti-gravity race track. The race track now has each half of the U-turn with different colors. The park background has gone through a lot of changes, such as the addition of a "Baby Castle" (which is a nod to Cinderella's Castle at the Magic Kingdom), new rides added like a haunted house attraction based on Luigi's Mansion, and some of the returning background rides being heavily redesigned, like the Bowser's Ship ride and the Ferris wheel, now resembling the Sun Wheel from Super Mario Sunshine. Also, the starting banner now shows Baby Mario and Baby Luigi with their shirts, overalls and shoes on as opposed to being solely in diapers like the previous versions. They also have been given slight animations that are found on rides, where they move back and forth.
The race on this course has seven laps just like in the original and the revamped music now increases in speed after every lap, making it the first retro course to do this. On the final lap, the guard rails light up and become multi-colored and like with remade N64 Rainbow Road, the last part of the music starts to play instead of the beginning of it. It is the only retro course and one of three DLC courses (along with Mute City and Big Blue) to be entirely an anti-gravity race track. This is the shortest track in the game and the only track with more than three laps/sections. Baby Park is also the only track in Mario Kart 8 where players cannot perform tricks.
This track, alongside the other DLC content, will be available in the core game of Mario Kart 8 Deluxe.
Several characters that are important to the Yoshi series appear to have their own rides around Baby Park. They are listed below.
