stick to one side of the tank by the ends of their flagellum if left alone. In this stage, the player's interaction is somewhat minimal and plays similar to a tutorial, allowing the player to learn to control the heat in the fish tank, direct the Mushroomers, and clean out any filthy water that has accumulated over time. After emerging from the deceased body of the nautilus, the organism enters a stage called the Gillman, which resembles a cyprinid fish with a human face and a tentacle-like tube atop its forehead. During this stage, the Seaman becomes capable of speech but can only communicate in gibberish by reiterating comments made through microphone input. At this point, the player will begin the communication process and continue maintaining the aquarium as the Gillman grows larger, developing scales and a larger vocabulary. As the Gillmen mature, they develop scales and more advanced speaking abilities, but they will soon kill one another until only two remain. Their genders are indeterminate until they mature to the point of being able to be named. Once one is named, it will change its color and sex. In its next stage, the Podfish, the Seaman is still fish-like in appearance and is similar to the Gillman but has gained frog-like legs. After mating, the male Podfish dies. The aquarium is also transformed into a terrarium: most of the water is gone, there is new land, and new breathable oxygen. The female then lays its eggs on the shore. Shortly after depositing the eggs, the female also dies, leaving the player a new generation of Seamen in a new evolutionary stage. Instead of the introduction of hatching as Mushroomers like the first generation, the player began the game with a new form, the Tadman. They superficially resemble the baby Gillman but instead of a fish-like appearance, they resemble tadpoles. In addition, they still retain the same deep voice that their parents had. As they age, their bodies grow larger and small limbs begin to form. The Tadman eats their fellow siblings until their number is reduced to two. When this happens, the siblings will climb ashore and walk on land, ushering them into their next evolutionary stage. The Frogman is the Seaman's final stage of its maturity process. It is an amphibious creature resembling a frog and like the Gillman, it has a human face and a tentacle-like tube
