His insane behavior is pretty much all the evidence you need. He is also "voiced" by Jerry Trainor, who was Crazy Steve on Drake and Josh.
Toonville is on a planet located near Earth.
A planet that was never discovered in the solar system, too.
Jossed. Lordryu confirmed Toonville and other universes are on an alternate Earth.
And then that got retconned in favor of Toonville actually being a country next to the United States.
The reason for the deaths on Final Procrastination were because...
...of the house fire in the party from the original show's The Pizza Problem.
Even though some of the people in that episode said they never even avoided a disaster, they probably forgot about that.
Plus, a couple of the people who ended up on Final Procrastination died in The Pizza Problem.
One of the partyguests who appear in Final Procrastination probably had a vision like in the actual Final Destination movies and got everybody else who appeared in the above New Series episode out, leaving everybody else most likely dead.
Hmm... that could make a good plot for a new Final Destination parody, perhaps a full-length movie on Fanfiction.
The original Toonville series (season 1 and the discontinued season 2) and its non-existent later seasons and movies are non-canon.
Maybe there's barely a reference to an original episode in The New Series and other Toonville-related fanfictions.
There were at least two episodes from the original episode that were remade and/or changed.
Toonville is actually All Just a Dream or a book written by someone who supposed to be Lordryu.!!
Technically, Toonville is a fanfiction, which is like a book, except made by a fan.
