Possibly one of the earliest attempts at cinematic product placement.
Ahh, Gamera. Zigra. Giant Turtle. Giant Fish. Fire. Hypnosis beams. I guess the pleasure from these classic japanese monster films is watching a world, or mostly Japan, where giant mutant monsters exist, children know much much more than the adults, and cities are crushed as easily as cheesy models...oh wait, they are models. Anyway, UFO comes to Japan. The main brats Kenny and Helen (will someone get her a coke already!!) go on zany trying to prevent Zigra and his scantily clad henchwoman (VA-VOOM!) from trying to take over earth. The Zigra woman has the ability to hypnotize people with a simple snap and she must follow Zigra's orders to kill the children who mysteriously manage to survive again and again (duh). People yell AH!!, Gamera shows up, Zigra blows stuff up, a lot of paint...uh blood is spilled, I think there were dolphins, and lots of subplots to keep virtually anyone watching perplexed. Also, the diabolically catchy Gamera song is sung here. Add this all up for a huge laughs and best seen with Joel and da bots (HEY, THAT'S US!!).
