Was Medialab involved in this special?
From The Lost Media Wiki
https://www.youtube.com/watch?v=GTupd9fidq0 I found this video on the YT channel of Fabienne Legrand, CG supervisor at Medialab, the production company responsible for the Donkey Kong Country TV series and the programming block DKTV, and both iterations of Bugs Bunny in the screenshot and the video look remarkably similar to one another, although in the screenshot the 3D model has better shading. Fabienne claims that the clip from Ca Cartoon is from 1991, six years before the special, so the leap in quality is to be expected.
