Blot in Space'), also known as Mr. Blob in the Universe, is a 1988 fantasy film directed by Krzysztof Gradowski [pl].

The Great Electronics Engineer, who had fled the Island of Inventors and settled on the distant planet Mango, is working on a groundbreaking invention—an apparatus for "phantomization."

After she is abducted to Mango, her classmates seek help from the reclusive Mr. Kleks, who lives in the last nature reserve on Earth.

At the film's conclusion, after the computer finishes recounting the story, two mechanics arrive, claiming they need to repair the machine.

Unlike its predecessors, Pan Kleks in Space did not draw from the literary works of Jan Brzechwa.

Despite this shift, the film includes references to earlier entries, particularly continuing the subplot involving the Great Electronics Engineer introduced in The Travels of Mr. Kleks.
