As they arrived at the doorstep of Sugarcube Corner, the Doctor remarked, "It's very pink."

"Yes sir, it most certainly is!" replied Derpy, seeming to be more excited about the fact that the Doctor was following her for once, not her following him like it usually was. They walked up to the counter and Mrs. Cake asked cheerfully, "What can I getcha?"

The Doctor asked, "Do you have any scones?"

"Oh yes," she answered. "Um... Oh dear, where have you gotten to now? I'm always losing track of the scones." She was rummaging through several different drawers and cases. She came back and said, "I might be out up here. But, I've always got more downstairs. Want to come?"

Derpy asked, "Do you have any muffins left?"

Mrs. Cake said, "Why, of course! We have nearly every pastry in Equestria and we almost never run out! Of course-"

But she was cut off by Derpy, who after hearing that practically screamed, "Great!! Let's go!"

As soon as Mrs. Cake opened the door to the basement, Derpy was at the top step and then tripped and fell all the way down. There were several crashes of cases falling over and cupboards opening and dropping their contents. Finally, a large thump came from somewhere downstairs. After an awkward silence, the Doctor called down, "Derpy, are you alright?"

After a few moments, there was Derpy's normal voice, saying, "Yes Doctor, I'm okay!"

"Oh my, I hope so!" said Mrs. Cake, sounding doubtful.

"Well, fancy that!"

Once everypony was downstairs, the Doctor saw that Mrs. Cake was right: there was every kind of pastry the Doctor had ever seen. Croissants, cakes, donuts of every kind, pies, apple fritters, cinnamon rolls, danishes, etc. And muffins! Thousands of muffins of every kind you could think of! And Derpy was gobbling them up at lightning speed, about a dozen in each mouthful. "Derpy... um..." said the Doctor, glancing over at Mrs. Cake. "This is actually pretty normal for Miss Hooves," she said.

Derpy came back and said "Itf gude!" through a huge mouthful of pecan muffins.

The Doctor looked over her shoulder and asked, "Mrs. Cake? Where does that door go?" He was looking at a really old door with rusty hinges and a nearly broken door knob.
Casually, Mrs. Cake answered, "Oh, that's just the cutlery storage. Ah, you know what? I might actually need a sharp paring knife. Care to join me?"

"Sure!" said Derpy enthusiastically.

So they started to walk towards the door.
