With Beavis & Butt-Head nearing the end of its initial run, MTV felt they needed to keep the animation train rolling. So they went back to the starting line.
Cartoon Sushi was supposed to do the same thing that Liquid Television did before it 6 years earlier, serve as a linchpin for a new wave of cartoons for the network. Where Liquid begat Beavis & Butt-Head and Aeon Flux, Sushi managed just one spin-off, that being Celebrity Deathmatch, which would outlive its parent show.
Danny Antonucci (ex-Brothers Grunt) designed the open as his last project for MTV before leaving to create Ed, Edd, & Eddy for Cartoon Network. Other than that, well, judge for yourselves.
I think Stick Figure Theater had started somewhere else before being picked up for Sushi, but I can't be sure about that. I didn't watch enough of the show to merit a rating, so there won't be one.
