It has been eight years since Buttonmash and the CMC have graduated school and moved on with their lives. Button is a famous videogame designer, Sweetiebelle is on tour, Scootaloo is a stuntspony, and Applebloom is working on real estate while expanding the CMC. The CMC are still helping others, but have jobs as well, leaving almost no time to be free. Button, under the pressure of designing a new game, has become anti-social, and has blocked everypony out to focus. Rarity, worried for Button, calls the CMC for help to bring the Buttonmash, that Ponyville knows, back.
