There was this weird phenomenon where a large portion of the SCTV cast got their own Saturday morning cartoons in the early 90's that I've never been able to find an explanation for.
There was a time in the early 90s when all cartoons sounded as if they had been voice recorded underwater. Hanna-Barbera must've been toying with some weird sound production at the time, because it carried over to Pirates of Dark Water too.
