Applejack's BBBFF

[EDIT] Check out this awesome vectoring job by Entity-Nate: fav.me/d6k7tzn !

I'm really surprised this hasn't been done before. This ideas been in my head ever since the end of Season 2. Why has no one else realised AJ has a BBBFF too?

This somehow looks better on paper than it did in my head, I'm just sorry I don't have a better way to colour them. And I swear they have freckles! I gave them freckles! They're just really hard to see now...

Lyrics:
[Applejack]
When I was just a child, I found it pretty wild
To do anything but work with mah family
So much work to do, didn't need anyone but you
No other ponies to make my life complete
You are the one colt that I care for
And I know you will be there for me
My big brother, best friend forever!
Like two peas in a pod, we did everything together
He taught me how to harvest trees (Best friend forever!)
And taught me my ABCs (We did everything together!)
We shared our hopes, we shared our dreams
We’ve drifted more than I realized
It seems...
[Rest of mane six]
Your big brother, best friend forever
Like two peas in a pod, you did everything together
[Applejack]
And ‘though I see him everyday
I hope I can still say
He’s my big brother best friend
Forever...
Forever...
