Godzilla vs the Smog Monster
Possibly the cheesiest, drug-induced Godzilla movie ever made. In this one, an entire montage of pollution scenes show the dilemma humanity faces in one of the most phoned-in messages ever put in a Japanese movie. Its then we are introduced to this rounds contender for baddest monster in Japan, a sludge tadpole. Seriously.
There is so much confusing crap going on in this one its impossible to not comment about it. The Smog Monster gets bigger by smoking a smokestack like a bong like its life heroes are Cheech and Chong, it apparently can shoot poop from its nipples, it can transform into a flying turd pile and spreads silent-but-deadly gas across Japan, and it seems to like going after teenagers whose sole purpose is to gripe about their angst and pollution.
But what about Godzilla? Well, he finally realizes how ridiculous the premise is and actually does a face-palm at one point. His monster destroying episodes are accompanied by the worst Japanese pop song ever sung in a monster movie. (Seriously, the song is even worse than anything put out by those tiny twin fairy chicks from the Mothra movies and that's saying a lot.) And did you know Godzilla can fly? Because he totally does in this movie.
This is considered one of the worst Godzilla movies to come out during the early days of the franchise, even by one of the creators of Godzilla (Tomoyuki Tanaka, respectively). Its overall camp, strange message, and target audience of children make this one really weird. If the guys ever get the time to do this Riff I would probably die a happy man. Of course, if someone else decides to do an iRiff I would watch it. I would just ask them to watch out for the poop nipple thing.
As much as I hate Godzilla movies, based on your description, this is one I actually would pay to see RiffTrax decimate. I can just imagine the mileage they'd get out of a turkey like this.

Oh YES! That song is so bad, it makes me want to drive a Nissan Diesel dump truck full of Dioxin and dump it in Downtown Tokyo.
Yes yes YES!!!
