I think I just found it after typing "pink rabbits and a robot anime" into Google: is it Usavich
?
Is it... Bunny Maloney? https://en.wikipedia.org/wiki/Bunny_Maloney
It's French cel-shaded anime-style CGI series with two pink rabbits, a rabbit/dog hybrid?, tanuki, and a human villain with a talking cat that seems to be a slice-of-life series as well as a Voltron-ish show with them fighting said villain in a giant robot. And, the running gag was that his ship would explode and sink to the bottom of the ocean? It was originally on Kix!, but resides on Kabillion now. (I frigging love the theme song.)

I'm not entirely sure if it was a dubbed anime or a western piss-take of anime, but it was this stylized CGI show about a trio of rabbits (one or more of which were pink) who piloted a giant robot against some other asshole who would constantly throw new robots into town to screw things up. This has been annoying me for ages and I need to at least know the name of this show. If you guys could help it would be massively appreciated.
