Meet the silliest, cheesiest couple in Equestria, party pony extraordinares: Pinkie Pie and Cheese Sandwich!
 
These two party ponies are perfect for each other. Their brand of comedy, their gags, and the parties are unmatched. They make the best party team. Of course, it wasn’t always like that. Cheese Sandwich arrived in Ponyville on the same day Pinkie Pie was planning a “birth-iversary” party celebrating Rainbow Dash’s birthday and anniversary of her move to Ponyville. The townsfolk, including the Mane Six, were entranced by Cheese’s partying and allowed him to plan the festivities instead, leaving Pinkie dejected. Refusing to be outdone, Pinkie challenged Cheese to a “goof-off” to determine who would headline the party. However, Pinkie soon noticed the strain that her prideful behavior was putting on Rainbow Dash, and forfeited the match. Her friends apologized for making her feel neglected, but Pinkie countered that it was her fault. Cheese arrived and revealed that it was Pinkie who inspired him to become a party planner as a colt. Pinkie and Cheese worked together to throw Rainbow Dash a spectacular party before Cheese departed. As he did, he left Pinkie his favorite rubber chicken as a parting gift. This parting gift would be one of the six keys to open up a mysterious chest that would grant the Mane Six rainbow power, defeat the evil centaur Tirek, and create Twilight Sparkle’s Castle of Friendship.
 
Pinkie would then meet up with her former rival again in a couple more moons later. She was to Cheese Sandwich’s very own prank factory! Dismayed that most of her friends had achieved their big goals in life and she hadn’t, she decided to take the opportunity to find her calling in life with him. Upon her arrival, however, Cheese and his overly formal assistant, Sans Smirk, explained that Cheese had become unable to laugh ever since they started the factory to satisfy widespread demand for his novelties. Pinkie devised modifications to several of Cheese’s pranks, but none of them would make him laugh. She eventually realized that he needed to see ponies laugh in person, and he regained his cheerful spirit after leading Sans and the employees in a factory-wide round of jokes. He’s shredding it again! Cheese took up his old role of a traveling party planner, leaving Sans in charge of the factory and promising to send back ideas for new products, and Pinkie returned to Ponyville with a new understanding of her purpose to make others happy.
 
After Twilight became the new ruler of Equestria, Pinkie and Cheese would see each other again, to work together in preparing for the Festival of the Two Sisters, formerly the Summer Sun Celebration, and the two party ponies were really starting to melt for one another like ice cream. There was a plague that kept Pinkie from admitting her burgeoning feelings for Cheese (this plague was sponging up everypony’s voices and every sound for miles). But Pinkie found a way to admit her love for Cheese, and they became girlfriend and boyfriend, and in time they got hitched! So now they have a foal they named Lil Cheese, and this family continues to bring joy and happiness across Equestria while bringing smiles to themselves with their love and laughs.
 

 
First of all, I want to apologize for the incredible delay, but I got busy with my other pics from before and I already finished the final card last night. Good thing I was scheduled for a haircut earlier in the day, otherwise this would’ve been even more delayed. The other reason for the delay is the choice for Pinkie Pie and Cheese Sandwich. After searching for different interactions, I could only find one, and to tell the truth I’m not totally confident with this, but time doesn’t care about anyone. I hope you approve you the vectors I made. The sentiments are not mine. I couldn’t come up with any good ones. Fortunately, :iconjaithedog: was kind enough to come up with some. They really seem to fit. If you don’t like them, then please give me feedback and make suggestions. Otherwise, thank you, Jaithedog! :D
 
And now, for the final Hearts and Hooves Day card! Get ready.
