Last night, I had a dream that I was at an amusement park that had just about every major entertainment company. (Disney, Nickelodeon, Dreamworks, etc.)
I think maybe the villains went to war with each other seeing that “Grogar” never brought them all together, and their war had an effect on all of Equestria turning it into a wasteland.
Right
It is. Fairly Oddparents was created by Butch Hartman who also created Danny Phantom, T.U.F.F. Puppy, and Bunsen is a Beast. Phineas and Ferb, Milo Murphy’s Law, and Hamster and Gretel were created by Dan Povenmire and Jeff “Swampy” Marsh.
The Hamster and Gretel finale song, It All Comes Down To This, but with Twilight as Gretel, Tirek as Mordros the Annihilator, and SpongeBob as the unseen alien.
