Oh my god, just imagine, what it would be, if pinkies hair would actually turn in to cotton candy?
Of course I could explain that: It is the shugar. She just eats too much and slowly turns into a living candycane. What to do? No more Cupcakes? No way! Ask Zekora for a Potion? Go on one last Road trip to Los Pegasus as long as she can't withstand the urge to eat herself? Maybe discord has the solution. After all, he was responsible for cotton candy clouds and choklate rain, ask him how to reverse that - but will pinkie then loose her chaos an become absolutely tidy and has no more funny randomness.... Oh my good, what to do?
