In 1991 NBC launched it's final cartoon to it's Saturday Morning Lineup called Gravedale High which featured actor Rick Moranis in an animated form as the principal of a high school for monsters and although Gravedale High was short-lived it is considered to be one of the most underrated cartoons of Rick Moranis's career

This lasted for one season and was never re-broadcast in the US after its initial nbc run. It was more popular in the UK and it is the only cartoon series Rick Moranis has ever lended his voice too. It did spawn a line of McDonalds happy meal toys (probably the shortest happy meal line ever, they were pulled after a few weeks).
