Toonville/WMG

Peter is a Time Lord.

 * How would he get all that stuff in Skating Retards and Total Chaos?
 * He may have a teleporter machine.
 * And how did he get that, then?!
 * The Engineer built one for him.
 * Then how does Peter get the money for all the stuff he found?
 * Everything's a lot cheaper nowadays.
 * Brain-Sucking! made Peter dash off "to everybody" as The Flash.

Chris Maclean and Meatwad's talk show in Toonville in the Making is the main plot of the fanfiction.

 * Considering their segments are the ones shown the most, this may be confirmed.
 * Although this may be true, other things are focused on in Toonville in the Making, like the Harold vs. Everybody chapters.

Lumpy is Crazy Steve in disguise as a moose.

 * 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.

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.
