Sugarcube Corner is featured in multiple episodes. Pinkie Pie bakes cupcakes there in Applebuck Season, and consumes desserts prepared for the royal visit of Princess Celestia under the pretense of being a food-taster in Swarm of the Century. The first floor holds a store-front, which is also used as a party or gathering space in several episodes, as well as a kitchen and a room with a taffy maker seen in Call of the Cutie. The second floor contains Pinkie Pie's bathroom, which is seen in Feeling Pinkie Keen, while the third floor in the building's cupcake-shaped tower contains Pinkie's bedroom. There are café tables outside the shop for customers to enjoy their treats right outside the store, which Pinkie uses in Griffon the Brush Off.In Party of One, Pinkie holds a birthday party for her pet alligator Gummy in her loft on the top floor. Twilight Sparkle also stops by the store to buy a cake for Pinkie's surprise party, which Pinkie Pie partly overhears through a hole in the floor of her room which seems to bypass the second floor entirely. When Rainbow Dash comes to collect Pinkie for the surprise party, she enters Pinkie's room through the balcony door at the very top of the building. In Lesson Zero, Twilight buys twelve cupcakes for a picnic with her friends, although Mrs. Cake gives her an extra one for free, making it a "baker's dozen".
In Baby Cakes, even more of the building is shown. Pinkie Pie serves a snack to Pound Cake and Pumpkin Cake in a previously unseen room across from the rear staircase that joins to the kitchen, containing a dining table and shelves of candy. There is another bathroom, where she attempts to give the baby twins a bath. Pound and Pumpkin share a nursery on the second floor where Pinkie Pie attempts to change their diapers and settle them down for their naps, although not before Pound Cake drags her from the room and down the stairs through the main floor. There is also another doorway in the second floor hallway but it is unclear what it leads to.Pinkie Pie's loft and bedroom are shown in slightly more detail in Pinkie Pride. She keeps her party cannon in a large cabinet next to her bed, and a short staircase leads up to the balcony. Along the staircase wall, Pinkie has hung various photos of the parties she's thrown, including the first party she ever threw, Twilight's welcome-to-Ponyville party, Gummy's birthday party, and Shining Armor and Princess Cadance's wedding reception.
In Filli Vanilli, Rarity tells Fluttershy that Big McIntosh's voice is alright and that she is no longer needed to lip-sync for him. Due to Fluttershy's disappointment, they agree to have her lip-sync for him one last time. During The Ponytones' performance, however, she gets carried away in her singing to the point where Big McIntosh can't keep up in time with her lip-syncing the words. She eventually knocks down the curtain, exposing herself to the audience, and although the ponies cheer for her, Fluttershy is overcome by stage fright and bolts out. Big McIntosh helps her friends assess the situation shortly before they follow.Equestria Girls: Through the Mirror, human Flash Sentry refers to this cafe as the "Sweet Shoppe".
