Aaahh!!! Real Monsters is an American animated television series developed by Klasky Csupo for Nickelodeon. The show focuses on three young monsters—Ickis, Oblina and Krumm—who attend a school 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 series premiered October 29, 1994, at 11 am on Nickelodeon. Running a total of 52 episodes over 4 seasons, the final episode aired December 6, 1997.
The episodes follow the adventures of Ickis, Oblina and Krumm, three young monsters attending a monster school whose headmaster is The Gromble.
The show is set in New York City, demonstrated throughout the series by the presences of the Empire State Building and the IND Subway System. The dump the monsters inhabit is implied to be Fresh Kills Landfill, but never explicitly named in the series. The monster community includes a working economic system using toenails as currency.
