Godzilla vs Hedorah is insane even by Godzilla standards, a surreal mix of monster mash, message movie, kiddie flick, 1960s educational shorts, groovy protest songs, go-go dancers wearing fish masks, terrible special effects and basic Sesame Street style animated inserts as Friend of the Earth Godzilla takes on a giant toxic flying tadpole that craps acid on him, drowns mah-jong players in excrement and farts deadly toxic fumes over the population of Japan. Introduced with a slide trombone theme straight out of a Laurel and Hardy get drunk comedy, Godzilla has never looked camper, mincing his way through his underpowered punchups with the allegorical scheissencritter – Hedorah is basically just a vertical turd with a tail and glowing red eyes. It's tempting to believe from the number of times Mr G wipes his nose that this was during the big feller's cocaine period, but he seems all too aware of the humiliation: at one point he even turns to the camera and shakes his head to the audience in disbelief.
