Aaahh!!! Real Monsters is an American animated television series developed by Klasky Csupo for Nickelodeon. The series is about adolescent monsters in training and originally aired four seasons of 52 episodes on Nickelodeon from October 30, 1994 to December 7, 1997.
The show focuses on three young monsters — Ickis, Oblina and Krumm — who attend an institute for monsters under a city dump and learn to frighten humans. Many of the episodes revolve around them making it to the surface in order to perform "scares" as class assignments.
The show is set in New York City, demonstrated throughout the series by the presences of the Empire State Building and "IND Subway". The dump the monsters inhabit is implied to be Fresh Kills Landfill, but never explicitly named in the series.
