Digestive: Tallians cannot digest solid food; consuming solids would likely be fatal for them. They rely solely on liquids for sustenance. All ingested substances, whether liquid or in a water solution, pass through a network of water channels that extends from their mouth, through their body, and exits through their root-like feet into the ground. As these substances travel through the channels, any water they contain is absorbed by numerous small protrusions along the canal. The absorbed water is then distributed throughout their body. This movement of water through the body is facilitated by the flesh molecules, which transport the water to various parts of the organism. The water ultimately reaches the skin, where it is used. Any residual components from the liquid are expelled through their root-like feet.
Lungs: As plant-based organisms, they don't need lungs to survive since they absorb carbon dioxide through their skin. However, they do have a small, lung-like pouch and vocal cords inside their heads, which are used solely for communication purposes.
Circulatory: The green flesh acts as a sort of circulatory system, where any glucose formed in the skin is shared among all the flesh cells and other organs, as they all need it to survive and function.
Nervous: Every part of the green flesh can sense pressure, temperature, and pain. Together, they function as a collective brain, so if Tallian loses a part of their body, they also lose a part of themselves. The flesh cells near the eyes and twigs have an additional task: processing images and sounds, respectively.
Skeletal: Their entire body is filled with thousands of thin bones, connected in a way that allows Tallians to move each part of their body fluidly and independently. They have a rib-like structure in their chests.
Special:
The Great Light Bringer created them with a special spherical organ called the
Spheritel, which enables them to communicate telepathically or, in extreme cases, even control others using it. The
Spheritel is located precisely in the center of the chest, protected by the rib-like structure.
