Forum Topic: What Ever Happened To Humans?
===My theory: During the mushroom war, Ice king went to Ooo for refuge from the Apocolipse(also b/c his wife dumped him, as seen in "Holly Jolly Secrets, Part 2"). Susan took refuge in a hatch with fish people during the mushroom war. With no other human to talk to, she lost her humanity. At the same time, Finn's family is in hostile hands. He is hid in the forest with his 13-year-old sister Fiona and the family pet, cake. A few years later fiona and cake dissapear and Finn becomes an official member of Jake's family(finn now has no memory of his true family). Ooo has no contact w/ the rest of the world, where there may be possible human survivors.===
