For the attack of the giant octopus, four live octopuses were used. They were forced to move among the miniature huts by having hot air blown onto them. After the filming of that scene was finished, three of the four octopuses were released. The fourth became special effects director Eiji Tsuburaya's dinner. These sequences were filmed on a miniature set outdoors on the Miura Coast. Along with the live animals, two rubber octopus props were built, with the larger one being covered with plastic wrap to simulate mucous. Some stop-motion tentacles were also created for the scene where the octopus grabs a native and tosses him. These sequences were shot indoors at Toho Studios.
