Spike had finally stopped chasing the mare of his dreams, Rarity, after an argument. Twilight suggested that he should go have some fun to take his mind off of it, so he attends a birthday party at Pinkie's.

Though most would just laugh at those ideas, they go through with them, and business begins booming.
