Where he had come from, nopony knew... though I once heard tell that he was banned from Manehattan
after his dancing for 25 and a half hours straight wrecked most of the city.
His goal in life was a simple one- to party everywhere in Equestria, then enjoy a good sandwich.
Of course, if one met him when he was in his "serious state", nopony would think he was a party-goer...and yet, he was.
His "Cheesy Sense" always pointed him in the direction of a party.
His sense was pointing him in the direction of Ponyville
His cutie mark
was in the shape of a cheese sandwich torn clean in two.
Likewise, he was just as excitable.
His riding companion was a rubber chicken named Boneless
He was... Cheese Sandwich!
He's a stranger, loose and running... but he's not here to do business with a big iron on his hip.
"Oh, I don't think so..."
"Hey, good-looking! Want some mayonnaise?
"You think you can out-goof me?"
"I don't think so, I know so!"
His pride insulted, Cheese Sandwich was itching for a goof-off!
"Nopony calls me boneless!"
Boneless had chosen to stay out of the argument.
Cheese Sandwich Dares to be Stupid!
Everypony and their fillies were watching with bated breath as Cheese Sandwich and Pinkie Pie strolled into town, wearing the most ridiculous get-ups, for their 3:10 pm goof-off.
"I was ready before I was born!"
Of course, Pinkie was unaware that Cheese Sandwich possessed the finest in party-related assault vehicles.
Cheese Sandwich had literally been made speechless.
His heart in a singing kind of mood, Cheese Sandwich decided it was time to share some information about his true past.
The truth was that Cheese Sandwich had not been born a party pony- cruelest fate had him born a super-shy nerd.
His shyness was too much for the poor foal to bear.
Embarrassed by his lack of a social life, Cheese Sandwich ran away from his home town
, searching for a better life.
So sad was he that he failed to pay close attention to his surroundings... including that random party hat in the middle of the path!
He found himself surrounded on all sides by ponies of different colors and species.
Thankfully, the aboriginal ponies bore him no ill will, offering him companionship and a cheese sandwich.
Also, the locals decided to truly welcome him with their "tossing our new friend into the air and hoping he sticks the landing" dance.
A rubber chicken had hit the young party-goer in the face...
...but he didn't mind. After all, that chicken had become a friend.
"Hey! You two should kiss!"
Where does he keep all these hats?
Cheese and Pinkie hosting together.
He had given the real Boneless to Pinkie, bringing #2 out as a replacement.
His work done, Cheese Sandwich packed up his party toys and rode off once more into the setting sun, on the road to the next big party.
