Aaahh!!! Real Monsters is an American animated television series developed by Klasky Csupo for Nickelodeon. It is the fifth Nicktoon after Doug, Rugrats, The Ren & Stimpy Show and Rocko's Modern Life. 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 their zany hijinks after making it to the surface in order to perform "scares" as class assignments. The series premiered on October 29, 1994 and aired until November 16, 1997
