东方的大海上，有座风景秀丽、灵气充裕的小岛“浮光岛”。三百年前，浮光岛涌现出许多妖怪作乱。猫猫神“岚”在山上的一棵古树下施法，祛除了它们。岛民为了供奉猫猫神，在古树下建起了“浮光神社”。自此，岛上有结界守护，妖怪很少出现。怀有执念的小猫却有机会化作人形、猫耳、猫尾的猫灵。
The Octopod is grabbed by a colossal squid. The Octonauts are unable to break free due to the hooks on the ends of the squid's tentacles. Fortunately the arrival of some sperm whales turns the squid from hunter to hunted.
