Octopod

"This is the Octopod. That's where the Octonauts are living in there. I like that. My kids love Octonauts. I like that too. That's what's been happening to parents like me loving cartoon characters. I must agree with this."

--Su Ji-Hoon, The Octonauts and the Great War

The Octopod is a mobile undersea vehicle, and it is the Octonauts' home and headquarters. It consists of several interconnected areas. It is built to look like a giant octopus. It is also nuclear powered, as it can travel around the world almost indefinitely.
