Yongary, Monster from the Deep (1967)
“He drinks oil from a can and eats dirt. He’s Barney, the purple dinosaur’s,
older, meaner cousin, Yongary!”
This is Korea’s foray into the Kaiju Monster film arena. A rocket launch awakens Yongary underground. Scientists track seismic activity until they discover it’s caused by an ancient beast moving underground. Yongary rises from the earth and destroys the city. After a lot of destruction, he needs a drink and finds a full tank of oil. He drinks it and blows flames. Then he drinks some ammonia and it doesn’t agree with him. He gets a tummy ache, dances around and gets angry. He breaks out in a rash and it 
makes him very irritable. When the scientists discover Yong is allergic to ammonia (it takes a young boy to figure it out), they make some ammonia bombs. They drop some bombs, Yong gets upset and destroys the bridge. Finally, he kicks the bucket.
A low budget makes for less detail in the special FX all around, which in turn makes them not-so-special FX. The Yongary costume has some basic flaws that sometimes makes him look like a guy in a costume at a children’s birthday party. The buildings look like toys in the close-ups because of lack of detail. The plot is simplistic and there’s not much of a human story to it other than the humans fight against Yongary. All this less attention to detail adds up to a film that is more silly than threatening. But it’s not a total loss, there’s some fun Kaiju destruction scenes and Yongary does breathe fire. Good times!
There was a remake of Yongary called Reptilian (2000) but it was a cheap CGI, badly written script, disaster that isn’t even fun to watch in a MST2K way. Stick with the original for some campy Kaiju fun.

Definitely campy, but a lot of fun.
Sounds like this one needs a return to the past! 🙂
