Pinkie Pie was bouncing along the street one day in ponyville, when she noticed something on the ground.
"Ooo! I wonder what this is? Is it like an alien poopohnoitcouldbeanaliencowpoop-" she went on like this for about 5 minutes.
She then picked it up, and proceeded to show it to everyone, naming it 'Gak'.
Twilight then came along and was yelling something about sombreros and hearts, but everyone ignored her because the gak was so amazing. You could squeeze it, stretch it, bounce it, feel it, pop it, it was so amazing that no-one noticed the Crystal Empire.
The Gak was just TOO AMAZING.
Then Applejack came along, and said "Hey Yall, I found this thingy here on the road." She reached out of her saddlebags and tried to show her 'Floam' to everybody, but no-one cared because of Gak.
THE END.
A/N The Gak commercials got more hype than the episode. I mean, holy ----. This is a total joke, do not take this seriously.
