Aqua Marine engulfed her brother, Mountain Peak, in a hug. “What are you doing here?!” she exclaimed. “Careful, you’ll blow my eardrum out.” He said playfully. “I came to visit you.” He said. Aqua Marine looked up. “But I thought you were climbing the biggest mountain in Equestria.” She said, puzzled. “Well, turns out it wasn’t exactly the tallest mountain. But once I do find the biggest mountain, I will climb it.” Pinkie Pie peered at Peak, with a strange expression on her face. “Wait, you are brother and sister, right? So why doesn’t Peak have wings?” she said confusedly. “I do, they’re just little nubs, see?” he said, twitching the little stumps on his back that were supposed to be wings. “Oh. I see now!” Pinkie said, hopping away. “Catch you later!” Peak smiled at Aqua. “Aren’t you gonna show me around?” he asked. “Umm… sure. But maybe Pinkie would be a better guide than me.” She said. Peak tipped his head to the side, looking confused. “Who’s Pinkie?” he asked. “She’s the mare that was just here.” Aqua explained. “Come on, you must be exhausted. Let’s get you a warm bed and something to eat.” Aqua said, shooing him into the house

The next morning, Aqua Marine trotted around Ponyville looking for Pinkie Pie, with Peak following. Suddenly, Pinkie seemed to pop out of nowhere, right in front of them. Peak jumped back, looking surprised. "It's okay, Peak. She does this all the time." Aqua said to her freaked out brother. "Um, okay, then?" Peak said confusedly. "Soooo, you want me to show you around, right?" Pinkie said, hopping in place. "Uh, yeah, I guess so." Peak replied. "Okey dokey lokey! let's go meet Fluttershy!" Aqua looked at Pinkie Pie confusedly. "but Fluttershy lives all the way on the other side of town..." Pinkie doesn't listen, she just hops away, humming a song. Aqua just looks at her brother, shrugs, and follows.
