In the audience stand at the beginning, new characters can be seen, like the Gingerbread Toad! While they have not been given an official name yet, they are clearly Toads made out of gingerbread cookies. These characters so far have only been created for use in Mario Kart, and whether or not they will make an appearance outside of the Mario Kart franchise is unknown at this point in time.
References to Princess Daisy
As mentioned above, Sweet Sweet Canyon has plenty of references to both Princess Peach and Princess Daisy. At the beginning of the course, the gingerbread men and gingerbread Toads can be seen towards the left of the starting line. They are standing in three boxes. The box all the way to the left has a pink and green color scheme, with magenta hearts on the bottom, referencing Peach. The box in the middle is orange and brown and has orange floral symbols on the bottom, referencing Daisy. The third box is not specifically based on Peach or Daisy, but has their Royal Patisserie logo on it just like on the other two boxes. The Peach and Daisy-themed boxes feature an alternating pattern of Peach's emblem and Daisy's emblem on the top of the boxes. The third box does not feature this pattern. (pictured above).
Shortly after the startling line, racers enter a tunnel composed of a sweet of some sort. A detail of note is the material used to line the sides of the tunnel. It appears to be a white lace-like liner, often found in table cloths or coasters. The pattern for this lace resembles a flower with eight petals. This lacing can be seen in other parts of the course as well, although it is most prominent here.
On the image to the left, a giant three-tier cake is can be seen, and players race around for a short portion of the course. The top of the cake features a crown. The green gem surrounded by petals on Daisy's crown can be seen, along with a ruby (from both Peach and Daisy's crown) and a sapphire (from Peach's crown). The bottom of the cake has donuts that are yellow-orange and green, which could reference Daisy's color scheme. Towards the top left of the image, on a piece of confectionery, there are flowers holding together material of some sort. The pink flowers come in five petals each, and appear to be blossoms, so are more likely referencing Peach and her affiliation with Peach blossoms.The giant cake itself is also surrounded by orange liquid, and giant green bottles with "Princess Orange" on it can be seen. The racers are not racing in water, but instead could be racing in orange soda or orange juice, making Sweet Sweet Canyon the only Mario Kart 8 course with an "underwater" section except the racers are driving in a different type of liquid.
Towards the end of the track, two gingerbread houses next to the windmills can be seen. Both of them share the same details, in which 5 cookies can be seen on either side of the rooftops, with a sixth cookie appearing on the front of the house. What's unique about these cookies is they are cut in a fashion that resembles Daisy's emblem. They have six yellow "petals" with a green center. Additionally, the door knob to the front door of the house has a mini-scaled version of this same cookie. Egg shaped lollipops can be seen next to these gingerbread houses in addition to other parts of the track. The yellow and orange lollipops reference Daisy's color scheme while the pink one references Peach. Another type of lollipop exists on this course, with a circular shape. Of note, some come in a green / orange spiral twist, most likely referencing Daisy's color scheme again (See gallery).
With all the references to both Peach and Daisy, this course potentially be the headquarters of Peach and Daisy's Royal Patisserie company. Many billboards throughout the course have to do with the Royal Patisserie. The Royal Patisserie is also referenced in various other courses in Mario Kart 8, and the Royal Patisserie itself even appears in two courses.
One shortcut is available on this circuit: a bit before the finish line, you can pass under a giant donut through a chocolate part thanks to a mushroom. You can see this shortcut on the introduction picture of this page.
- This circuit contains 25 coins and it's length is 3 km.
- Daisy has had a previous connection with candy and sweets, as shown in a sponsor on Daisy Circuit in Mario Kart Wii (Daisy Candy). Also, on the same course there is something that looks like a shop with the text "sweet cake" and Daisy's emblem on it. Whether or not this served as inspiration for this course is unknown.
- The pink sky on top and orange liquid on bottom are the courses' two primary background colors. This may be in reference to Peach and Daisy's two main colors (pink for Peach and orange for Daisy).
- Sweet Sweet Canyon is referenced in Sunshine Airport through an ad on which one we can see Peach, but the intercom allow us to hear "This is the final boarding call for Boomerang Bros. International Airline, Flight 117a to Sweet Sweet Canyon, departing from Gate 3". This is inconsistent with the board before the finish line, which says flight "Sweet Sweet Canyon BBIA 4300."
- Sweet Sweet Canyon has some resemblance with Cookie Land from Mario Kart: Double Dash!!, Tart Top from Mario Kart DS, Sweet Mountain Zone from Sonic Colors, and Sugar Rush from Wreck-It Ralph.
- While Sweet Sweet Canyon is not named after anyone in particular, all the references to both Peach and Daisy suggest this course may belong to both of the princesses.
- The hot-air balloons which can be seen in the sky of the circuit have the exact shape and pattern as the candies present on the Daisy Candy sponsor panel in Mario Kart Wii and Mario Kart 7.
