There’s no doubt, friendship is the best thing ever. But friendBOATS are great too!! — Pinkie Pie
Coming in Season 6: Pinkie Pie will discover that there’s nothing quite as fun as rowing a Swan Boat through Manehattan with best friends!! You get to see the city from new and different angles, and it’s a fun way to explore Equestria together!!
