GO PONYVILLE! YEAHHHHHHHHHH!!!
Pretty much sums up the episode and why it was good, Biceps is totally a great side character and glad they did more with him. Also Applejack force feeding everypony her new fangled healthy foods. I think the best of the whole episode was how Twilight let Rainbow's decision to her and didn't tell her what to do, knowing not to get in the way so she would realise that her friends were even more important than her rolemodels.
The picture at the end was definitely one to save. I love how in the first series Twilight probably would have never worn something like that on her head. Pinkie Pie's influence for sure!
