The Impossibles are caught in a web of trouble when they face off with the Spinner in this installment. This episode appears on Saturday Morning Cartoons: The 1960's: Volume 1, along with the trio's battle with the Bubbler (previously reviewed) and a Frankenstein, Jr. short.
Note that when narrator Paul Frees (also Fluid-Man & Big D) introduced the heroes, the "The" was added to Coil-Man (Hal Smith) and Multi-Man (Don Messick), but not Fluid-Man. It's rather unusual, actually, since normally there were no adjectives for any of the guys.
Now, don't ya just wish they finished any of their songs?
