Description

Pinkie Pride.A party planner named Cheese Sandwich arrives in Ponyville on the same day Pinkie Pie is planning a "birth-iversary" party celebrating Rainbow Dash's birthday and anniversary of her move to Ponyville. The townsfolk, including the girls, are entranced by Cheese's partying and allow him to plan the festivities instead, leaving Pinkie dejected. Refusing to be outdone, Pinkie challenges Cheese to a "goof-off" to determine who will headline the party. However, Pinkie soon notices the strain that her prideful behavior is putting on Rainbow, and forfeits the match. The girls go and apologize for making her feel neglected, but she instead counters that she's at fault; however, Cheese arrives and reveals it was Pinkie who first inspired him to become a party planner as a colt. Pinkie and Cheese work together to throw Rainbow a spectacular party before Cheese departs, leaving Pinkie his favorite rubber chicken as a parting gift.
