After the Everfree funeral for Luna, Pinkie Pie devoted much of her time reforming the tantabus she used to take her place in the physical while she toured dreams. It took her a few weeks to change into the version of Pinkie that most Everfree ponies knew, to a degree. The tantabus Pinkie appeared to be much more approachable, and wore a warm smile a lot more often. Even with those changes, the tantabus was still sarcastic to a fault and enjoyed teasing young mares. After Pinkie was restored in a way, she, much like Fluttershy and Rainbow, avoided much of the drama that followed their dramatic reveal to the world outside.
Instead, Pinkie focused most of her efforts into the squashing of all the traumatic nightmares that followed the wake of their victory. It was a day and night obligation, one that her friends couldn't talk her out of. And in the end, Pinkie by herself slowly turned the opinions of many Equestrian ponies simply by granting them restful nights. With nearly three straight months of dream walking, she was finally talked out of her efforts to expend her abilities. Pinkie was inevitably talked into the cultural exchange by Applejack, who was already a part of it.
Without much else to do, Pinkie joined the hoof full of ponies that signed up for the exchange. Deciding to taking up baking in the process, she found it came easy to her, and built a local reputation for her confectionery sweets. Sweets Pinkie used to further Everfree and Equestrian relations in the small town of Ponyville by hosting multiple parties that would last through the night. Showing that everypony loved to party, even if she sometimes drifted off from the parties that she’d organize, the meaning still wasn't lost on everypony else who enjoyed their time. Pinkie Pie slowly found acceptance for what she was, and that was enough for her to dedicate even more of her time to the happiness of others.
