퍼즐 오션:고양이의 튜브

Humanity will develop anti-aging drugs. However, after a few years of development, mankind finds out that there are fatal side effects of anti-aging drugs... This side effect of returning adults to young children has caused a lot of chaos in society and also led to the regression of intelligence for the majority of mankind. . And, as another side effect, some cats were given an increase in intelligence and behavioral changes similar to those of humans. I wondered if mankind would face a catastrophe without even having the capacity to worry about this situation... But fortunately, cats took the side of mankind and researched substances that could treat side effects, and finally found a solution. When the cats find out that the material of the substance exists on the sea floor, they ride a specially designed tube to rescue them... But the process does not go smoothly. The reason was that someone was trapping the tubes by drift ice the moment the cats entered the seabed. Before the cats come up from the undersea expedition, collect the tubes trapped in the drift ice and give them to the cats.
