Twilight: Applejack, you got have to reach the shore and get help. We all fell victims to a curse that is transmitted via touch. This curse will strip you of your humanity and turn into a mermaid. I accidentaly discovered it as I touched Pinkie Pie and she transformed into a mermaid. Then she touched Rainbow Dash and she developed a severe case of leg envy and proceeded to look for and turn Rarity too. Go and look for Sunset Shimmer, she can help us defeat this curse. I will restrain Rainbow Dash until you are safe.
Rainbow Dash: NO! This is not fair! I had awesome legs! Why does everybody get to have legs but me? I need to…. I need to turn them… I will turn our friends into more of us…
Twilight: Rainbow, stop, you are not like this. Please, calm down, we will find a way to be ponies… I mean… humans again. Desist, please?
Applejack does not grasp the full situation but she continues swimming upwards…
