Aftermath and influence The Green Slime was used for the pilot episode of the film-mocking television series Mystery Science Theater 3000 in 1988 on KTMA. The episode differed from others as it lacked the character Tom Servo, instead featuring a puppet named Beeper who only spoke in beeps that Crow T. Robot could understand.
