It's all Matthew's fault, really. And Oney's. Allow me to explain: first things first, you'll need to watch Alpha One's Quantum Shampoo, and take special notice to the cgi title sequence, which was kindly created and animated by Matt. In order to keep track of all the different cgi elements for the sequence, Matt named all the bubbles, giving them the designations Bubble-01, Bubble-02, Bubble-03 etc. etc. You can see where this is going... Someone (I can't remember who) suggested that the name Bubble-07 would be a good premise for a story. I started to write a story, but got 'writer's block' two episodes in, as I'd backed myself into a bit of a hole story-wise.
So, I present, Bubble-07: All Two Episodes Of It.
There was talk of Bubble's continuity being resurrected in 2010, but it never came to anything, so when Fort Paradox was being developed, we decided to include Bubble in that, instead of trying to milk out a story from the ruins of the failed comic.
