Tropical Antarctica. The episode is set in Antarctica, 100 million years into the future. The episode focuses on five species: (1) Roachcutter, a descendant of an undisclosed sea bird and one of the first species to colonise Antarctica. It feeds on the insects of the forest and flies incredibly fast and with brilliant agility; (2) Spitfire Bird, a descendant of an undisclosed sea bird which collects chemicals from flowers of the Spitfire tree which it then spits at enemies; (3) Falconfly, a descendant of the wasp which feeds on birds; (4) Spitfire Beetle, a beetle or mantis that gathers in groups of four to take on the appearance of a Spitfire flower.
