The two ends of the earth are what we know as the North and South Poles, and the North Pole is a vast ocean, covered with thick ice, and many animals live, such as polar bears, arctic foxes, arctic wolves, beluga whales, narwhals, and so on. But in Antarctica, there is Antarctica, the seventh continent in the world, and of course, the land of Antarctica is also covered with a thick layer of ice, and millions of years of snow have accumulated to form a thick, extremely hard ice sheet. On the ice sheet live the familiar Antarctic emperor penguins, which are cute and cute, as well as seals, Antarctic wolves, krill and so on. However, just below the ice sheet several kilometers thick, there are many ice caves that crisscross and lead in all directions. In this unknown space of mankind, there lives a mysterious race, the Nemo. The Nemo people are naturally relatively small, the height of adults is about fifty centimeters, they are the same as humans, they walk upright with their feet, their hands can flexibly use various tools, a pair of big dark blue eyes, a high nose bridge, a small mouth, very cute, and the difference between humans is their blue skin. The Nemo people live in the intricate ice caves and underground under the Antarctic ice sheet, some of which are very large, forming villages and cities, and the Nemo people live in houses made of ice, and they will go out in powered sleds or unpowered skates.
