Toonsylvania

Toonsylvania is an animated television series, which ran for two seasons in 1998 on the Fox Kids Network block (usually placed in a block called "The No Yell Motel" that contained other scary kids' shows such as "Goosebumps" and "Eerie, Indiana") in its first season, then was moved to Monday afternoons from February 6, 1998 until January 18, 1999, when it was cancelled. It was executive produced in part by Steven Spielberg, as DreamWorks' first animated series.
The show had recurring cartoon series that appeared in each episode. (Unlike "Animaniacs", "Toonsylvania" did not have a wide range of characters and almost every episode had the same content.) The main segments were "Frankenstein", "Night of the Living Fred" (most episodes on season one), "Attack of the Killer B Movies" (some episodes from season 1), "Igor's Science Minute", and "Melissa Screetch's Morbid Morals".
