-The part of Splinter will now be played by a little boy who thinks he's a Turtle. He will probably get kidnapped a lot.
-April is now a waitress or something.
-Whenever there's a song, Leatherhead will just show up for no reason. Under no circumstances may he do anything that would justify or explain his presence.
-Vikings everywhere. Shredder? He's a viking now. Irma? She's a viking now. New York City? Now a really fat viking.
-The turtles are always incredibly fucking happy about everything. It's going to be a little unsettling when we get around to dubbing the episode about April's miscarriage.
