Pinkie pie playing with some.... Gak
Song made by Triangle and stormwolf
For people that don't understand:
Gak is some weird slime toy. The airing of the commercial for this product in between the long awaited season 3 episode somehow caused it to get stuck in peoples head and also ended up getting more airing time then the villain. Causing this likely short during meme.

gak! gak! gak!
