"Dragon Quest" Takes Place Before "A Friend in Deed"

Note how Cranky Doodle Donkey appears and is still traveling, whereas he settled on Ponyville in "A Friend in Deed". Also note how he has his old toupee. It's also interesting that this happened, because on Friday night, I had a dream that in the beginning of "Dragon Quest", Twilight Sparkle, Rarity, and Rainbow Dash would sing "Smile" for no reason. Those three turned out to be the main ponies in the episode. I am psychic O_O
