The main ending credit song for this movie is sung to the tune of "We Are Champions" by Jae Hak Lee from The Little Penguin: Pororo's Racing Adventure. As such, it is visually similar to The Little Penguin: Pororo's Racing Adventure.
Although Nature Cat got the medal from Manny before he and Willy left, Squeeks had Manny's medal in her hand. It's unknown if Nature Cat gave it to Squeeks offscreen.
The other racers are heard speaking during the party and the cave course of the race, but their voice actors are not credited in the end credits for unknown reasons. However, the international versions do credit the actors of the other racers who are heard speaking during the party and the cave course of the race.
The UK version came out only one day after the original USA version. It is rated PG in the UK.
Ronald does not bully Nature Cat and his friends due to Dandy taking his place in this film.

MC Ferret makes a cameo in the crowd during the victory celebration, cheering for Nature Kitten, Martin, Hal, Squeeks, Norman, Daisy, and Nature Cat. The same goes for the 4 band members of Dog Gone, Tanya the orange cat, Vincent, Jimmy Cat, and Granny Bunny.
A parade and a party took place on the eve of the Super Car Race. Dandy also speaks like Pete from Disney.

The second announcer was originally going to be a Mallard, but got replaced with a bear at the last second.
