The Duck children race against each other in homemade karts.
Behind the scenes
This short was released in 2014 on the Polder Animation website as well as the official Dutch Donald Duck website. It was created by Polder Animation to promote the game DuckWorld Adventures, and thus uses the animation style of the game.
Interestingly, the cartoon (along with the other DuckWorld cartoons the three appear in) is the first, and so far only, 3D CGI animated appearance of April, May, and June, and their first non-cameo animated appearance in general.
