In total, 102 episodes were made and ran from 1986 to 1990. Cast interviews since the show ended have revealed a few details about making the series: to make room for the puppeteers, the entire set was built on a raised platform with dozens of trapdoors in the floor. The trapdoors had to be reset multiple times, sometimes during a single scene, forcing them to shoot each episode over the course of several hours and without a studio audience.
