<P> During the miniseries "Islands", Finn being the last human was completely dispelled . It was revealed that around 1,000 years after the Great Mushroom War a group of surviving humans left Ooo and moved to a chain of islands . After many generations there are still humans there . Finn's mom Minerva is on Founder's Island, one of the islands, and was a Helper (doctor). She uploaded her mind to a network of robots after the island was ravaged by an illness . In addition to meeting his biological mother, Finn met many other humans . Although Finn hopes they may venture out of the islands and back to Ooo one day, people are changing their minds about leaving . </P> <P> Finn is a 5 - foot tall teenage human . He has several missing teeth, yellow hair, of which the length differs due to occasional haircuts . His eyes and eyebrows appear black from a distance, but according to lead character designer Andy Ristaino, they are blue . He wears a white bear hat, short blue pants, and a light blue T - shirt . He also has a green backpack, black shoes, and socks rolled down to his ankles . Finn has peach color skin . Finn is a teenage boy who is average height and weight . His arms and legs are very thin, but he has a wide torso . He is missing several teeth because they often face monsters that hit him in the face, also he often bites rocks and other hard objects . These teeth are sometimes round or pointed and constantly changing place, depending on the occasion . In the episode "The Enchiridion!" it can be seen for a moment that his left eye is green while his right eye is blue, as if he has heterochromia . However, Andy Ristaino confirmed that this was a "special occasion" and that in fact both eyes are light blue, which is not visible to the naked eye . He also points out in that episode that Finn had a small round nose but this is considered more of an error or humorous scene . </P> <P> In "Escape from the Citadel", Finn had lost right arm after it was pulled off after an attempt to reach his father, which was then coated by the blood of a Citadel Guardian that made it grow into a small flower . He later got his arm back in the episode, "Breezy," where the flower stub matured into a tree and broke away like a cocoon, revealing a new limb . In the seventh season finale, "Reboot", Finn lost it once more when his grass arm tries to attack a savage Susan and transforms into a sentient grass being called Fern the Human . Starting with the eighth season premiere, "Two Swords", Finn has been fitted with a new robotic arm by Princess Bubblegum, who fastened it in his amputated part since his old arm was no longer part of his body . </P> <P> According to Jake, Finn is about 5 feet (1.5 meters) tall . This is revealed in the episode "Dungeon Train", in the second half of the fifth season . In the 23rd episode of the sixth season, The Pajama War, it is seen that he has grown considerably, being almost as tall as Princess Bubblegum, who, biologically, is many years older than Finn . </P>
