1) Would you rather meet pony Derpy in Equestria or human Derpy at Canterlot High?
Personally, I would pop through the mirror portal and go meet pony Derpy and little Dinky too.

2) Would you rather only eat muffins for the rest of your life or never eat muffins again?
I would eat muffins. There are so many varieties that you couldn't get bored of the taste .

Feel free to make your own, but keep them Derpy related!

1) Me too, I think Pony Derpy wins hooves down, even though with the sweetie/cuteness of both Derpy and Dinky I'd probably end up dying from the cute factor overload because the two of them together beat the CMC in 'pony cute'.

2) I am not a big muffin fan personally, but if those were the only two choices then I'd go with eating muffins.
