An enhanced version for the Spectrum 128K was also released, titled Sweevo's Whirled.

It's up to the robot SWEEVO (Self Willed Extreme Environment Vocational Organism)[1] to clean the place up and thereby achieve Active Status.

Sweevo must find and destroy the malfunctioning Waste Ingestion and Janitor Units ("Wijus") that are supposed to keep Knutz Folly clean, while avoiding various hostile creatures and structures.

Among the other characters inhabiting Knutz Folly are the Goose Which Laid The Golden Erg (sic), the Horrible Little Girls ("Minxes"), and the Goose-Stepping Dictators.

Sweevo's World received positive reception from video game journalists.
