The episode is set in the northern forest, 200 million years into the future. At this point in the future, there are no mammals, birds, reptiles or amphibians. There are very few fish. The episode focuses on five species: (1) Lichen Trees, a group of species evolved from simple lichens. Some species are small bushes while others are giant tree like creatures. (2) Forest Flish, a smaller species of flish with hooks for feet so it can hang upside down on tree branches to rest. (3) Megasquid, a five-metre-tall (16 ft) squid with rhino-like skin and three-metre tentacles which patrols the forest. Its eight boneless legs are packed with muscles that act like bones. (4) Squibbon, an arboreal species of squid that swing through trees and have stereoscopic vision. The Squibbon could well be the next sapient life on the planet and create new civilization. (5) Slithersucker, an arboreal species of giant slime mold. Predatory by nature and reproduces by taking control of huge Megasquids.
