A New OneShot

So i promised myself going into all this that I wasn't going to use any known characters, especially in stories that just wouldn't happen (Clopfics especially). Today i find out i am horrible at lying and so I am doing Spike's Quest: The Search for the Mustache of Awe (working title). Here is a little taste, to the imaginary people that read this:
It is said a mustache is what ye seek
So do come closer, and hear me speak.
Long ago when mustaches flowed
Two were worth their weight in gold
Brindle Young worked to lower taxes
Yet on his face a most glorious mustache relaxes
Top Notch was a dapper fellow
Who, while mysterious, had a voice that bellowed.
These two shared a curious secret
That dated back to Star wirl the Bearded.
For you see Starswirl was on the frontier of all new magic
And when he heard of mustache’s he had to have it
But alas he was old and only grew a beard
So he devised a serum to create the thing everyone cheered
A drop of lotion, a dab of spice
And some bugspray to keep out lice
Making a beard potion was an easy feat
And magic made it all complete
These two set out years before
To find the potion of glorious lore
They found it in an enchanted spring
But to other’s faces had the potion cling
So they used what they needed, and a little more
Till the bottle was almost no more
This lasted them a long while, till late in their years
When old age had brought them all of their fears
Their manes had withered, their beards fallen out
They knew what they must do, beyond any doubt
The two met at the spring, and started to fight
And a battle of epic proportions raged on all night
The bottle was lost, nowhere to be found
The two tired ponies left without a sound
Now many years have passed, and the spring has dried up
And only two drops are left, so go find it, hurry up.
