The Mew Mews are enjoying a day at the beach as they take to the ocean on a motor boat. They then fall asleep, however the boat is pulled out by the waves and when the Mew Mews wake up they find themselves far from the beach and they come upon a storm where they fall over board and wash ashore, stranded on an island called Skull Island where they encounter several prehistoric creatures and a giant ape called Kong, who is the god of the island. While on the island the girls learn that while Kong is the Guardian God there is also the "Devil" who lives on the island. This gets the attention of Kishu who wants to take control of the this "devil" creature to one-up the Mew Mews. Meanwhile Ryo and Keiichiro, with the help of a sea captain named Englehorn, go out to find the girls.
