Cover art by Rvceric.
That is one amazing cover! Was it a commission? Lightning Dust is so cool! <3 Is she in this one? LET'S FIND OUT! *dives in*
Seriously, sweet cover!
Well, that was interesting. Sports gear morphing with the girls? Hasbro's gonna be upset if they can't patent that! lol xD
I'm guessing the power boost of Twilight's bond with the girls is probably why they got their Rainbow Powergrade in the last movie (aside from the obvious "SELL MORE TOYS" marketing reason) and since she's not around, they don't share in that new power she brought along with her from Equestria, leaving them with just normal Rainbow Magic butt-kicking leftover magic side-effects of the original magic from Twilight's element when they all came together*?
*takes a breather*
Short little Day by Day stuff? Neato.
(*and that's how I justified the logic in this fic. DONE!)
Not a bad start.
Oh, the girls riding motorcycles is gonna be SO AWESOME!
Especially Sunset...
5789023 Wasn't a commission, I just thought it was appropriate!
Nice job!!!
I have a question for you though...
)
Wouldn't Rainbow Dash be playing in the soccer game? (It's probably something really obvious
That's some soccer game!! 24-15!!!
Nice story!
Awesome chapters! I was actually thinking of using that cover, but since you used it... oh well!
I might do an audio reading of this later on.
5789673 No way, person!
Do you really think Hasbro would have her play plain old soccer over Motorcross? 
5789916 And thus Sunset comes to the rescue!
5790078 Really? Cool!
5790207
It's gonna be SO AWESOME!!
5791142 Thanks!
I love your revision of Awesome as I wanna be, really enjoyed!
And no rainbows this time? 
hmmmm....
*Whew!* I was beginning to think things were not going to end up well for Rainbow Dash
Go, Sunset, go! But seriously, Dashie, don't do that to us again 
5791213 Thankies!
Plot holes in a nutshell. Also, nice story
5793415 Thank you!
Could you give Zero a secondary role in these stories? He has a huge crush on Pinkie, BTW.
5794940 This is going for canon, no OCs. Sorry.
5795069 Oh. Well, could you do it in a later story?
5797752 Maybe.
5797979 Kewl. Could he at least be a background character in the shorts?
So much rule violations! Indigo Zap isn't having the best of luck today, is she? Nice story, Abbeybunny13!
5816474

Cool chapter!
5816895
Haha, I guess you should be thanking Abbeybunny! 
Thank you!5816918
Thank you, Abbeybunny for the great chapter!
Why is it that I can imagine one of these two being voiced by Cree Summer?
5816987
Thanks!
5818287
No prob!
5817779 No idea who that is, so I'll leave you to your speculation.
5818382 Take a listen to these, maybe you'll have heard at least one of them.

5818589 Sounds familiar, kinda!
Yes, I am the first comment! And that is sad considering that's the highlight of my day....
RR was 'Pinkie on the One' and now it's 'Pinkie on the Run' right? But nice chapter, I especially loved the part with confused Twilight.
5819427 You caught it!
Have a cookie!

Rarity's such a girly girl, but then again, so am I 
5820323 That's awesome!
5797979
I can imagine rainbow dash and sunset shimer pairing up for motor cross
5824852 They are, in canon!

Okay, I'm totally using that!
Poor Sugarcoat...

6106653 Thanks!
Bacon Head + Motocross = Win!
So what will happen here now thst TFG are out? Is it gonna be finished?
6476194 Probably canceled.
6479135 aww. Ok.
You should continue the story. People who cancel their stories don't have the honor of being bronies. That is all.
