Set a few years into the future, six year old Pound and Pumpkin have a lot of growing up to do. They fight and make up, make mistakes and learn lessons, and love and protect each other as much as they get on each other's nerves.
Andy just wants to try and relax one sunny day, but Pinkie Pie wants to know why he hasn't lived up to his Pinkie Promise. (This is the one where all is unfolded!)
Pinkie Pie has Passed away. After the funeral, the ponies of Ponyville put it upon themselves to bring a little party and laughter to their quiet town.
