GCN Baby Park

Baby Park is a race course that has appeared in Mario Kart: Double Dash!! and Mario Kart DS. Being a simple oval loop with no hazards, it is the shortest course in length in the series, 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 series. 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. However, the roller-coaster was removed in the DS version.

Appearance in 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 series on it, including Baby Mario and Baby Luigi, to whom the stage belongs. Due to its length, this course has seven laps instead of the traditional three. DK Mountain can be seen in the background.

Staff ghost
The staff ghost of the track uses Baby Mario and Baby Luigi, driving the Goo-Goo Buggy. They appear when the player completes all the race in 1:14.000 or less.

Appearance in 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.

Staff ghost
50.920 seconds using Toad in the Mushmellow.

Appearance in Mario Kart 8
Baby Park will reappear in Mario Kart 8 as a heavily-revamped DLC retro course. 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 background has gone through a lot of changes. The race on this course will have seven laps just like in the original.

Cameos
Several characters that are important to the Yoshi series appear to have their own rides around Baby Park. They are listed below.
 * Baby Bowser appears on a ship, with a sign reading "Baby Bowser's Ship". In the Mario Kart 8, this is replaced with Bowser Junior on Bowser's Ship.
 * Kamek appears above a sign reading "Kamek's Magic Show".
 * A Pink Yoshi Train in Mario Kart: Double Dash!! appears to ride around on an orange track, as if it were a roller coaster. It is seen in various parts of the Park, and sometimes it can appear above it. If it does do this, it may actually reflect off shells.
 * A large Poochy-like house appears far in the background.
 * A Helicopter just like the one from Yoshi's Island can be seen at the background, flying around the track.
 * Two large Shy Guys can be seen.
 * A Paratroopa can also be seen.

Official descriptions
Mario Kart: Double Dash!!
 * US website: “It may look easy, but Baby park is a 7-lap cage match with 14-monster Power-slides! There are plenty of items to pick up, and the long straightaways make easy targets out of everyone.”
 * European website: “It’s Mario Kart: the theme park ride! The track is a simple oval, but the power-ups are plentiful, so you’ll have a battle on your hands to finish in first place”

Mario Kart DS
 * European website: "It's the shortest and simplest track of them all, but Baby Park isn't child's play. Because of the circuit's great size you're given five laps instead of three, but make sure you put petal to metal from the word go, as it'll be over in seconds rather than minutes."

Trivia

 * In Mario Kart: Double Dash!!, it is possible to hit the roller coaster running around the circuit before the second bend of a lap, but it is extremely difficult.
 * Baby Park, having seven laps by default, is the only course in Mario Kart: Double Dash!! besides Wario Colosseum to not have three laps.
 * Baby Park is one of only two courses in the series that differ in lap count between its original and remade versions; the other is Rainbow Road from Mario Kart 64, if one does not count adjusting the number of laps in Quick Run mode in Mario Kart: Super Circuit.
 * The volcano from DK Mountain can be seen in the background next to the Poochy House.
 * In Mario Kart 8, it is the only retro course to be entirely an anti-gravity race track, just like the DLC course, Mute City.
