Scarcrow's Sig would be less scary. What if the Ponies were all transformers that forgot how to transform back to their bot modes? See: http://inspectornills.deviantart.com/art/Transformares-Fluttershy-244755340 http://inspectornills.deviantart.com/art/Transformares-Rainbow-Dash-244573915
Then you would be fabulous! (even more so than you already are) What if the clouds were really cotton candy, and the rain tastes like soda pop?
it would explain why can't breathe when you leave earth. but we would be pearless D: all the other oysters would make fun of us. What if cows actually made chocolate milk but it's just unchocolated before they sell it to us?
Then that would make the incredibly low price of milk even more incredible. What if owls grew on trees?
then the debate of whether owls are fruits or vegetables would be even stronger then it is today. What if, birds decided they wanted to be the earth's dominant species?
We'd have no choice but to submit to their fowl will. What if we all lived in pineapple under the sea? (I hate that show but that part of the theme is always stuck in my head)
well most of us would be forced to move on account of the not enough air. but also I would end up homeless very shortly afterward because I would eat my delicious house. what if, the show wasn't even real we just imagined it and no one has the heart to tell us we are crazy?
well then everyone else would be super crazy. like really really crazy. what if, pegasus can't actually fly, they can just jump really high.
Then that be a change of continuity just like Superman going from giant leaps to flat out flying. What is Pinkie Pie was a Pegasus?
