Arkie lives with her father Blister, a giant octopus, on the Peninsula. They help plants recover from the loss of electricity that affects them. Meanwhile in the City of Light, Dr. Maybee is precisely using this electricity for his experiments: he also needs octopi to help him recreate his lost daughter. Chihoohoo and his team, as well as Bunniguru and his Egg, go to Peninsula in search of a giant octopus for which they were promised a reward.
