Ponies attending Derpy's birthday party at Pinkie Pie's place! March 1st is "Derpy Day". Pinkie Pie handles the music with Gummy on her head. Applejack and Rarity exchange friendly nuzzles while Rainbow Dash hovers over them, watching blushingly. Derpy enjoys her birthday cake. Fluttershy looks around shily while Angel dances on her back. Applestack does the 2-legged Derpy dance while Surprise dances alongside a Dashy fan. And finally, Berry Punch (far right) invents a new way for drinking punch.
