I found the word Shellian in the 5th episode of Jazz1..... it didn't say that Shellian was the name of Devan's planet, but it was more like the turtles on Devan's Planet wer called Shellians. It said something like: Can Jazz destroy the Shellian Terrorists?
Well,maybe it's more like Devan's assistant turtles who are Shellians. Anyways, if anyone has another suggestion about something they found on Devan's Planet's name then you can still post here....
