"The Smile Song[2] is a song featured in the episode A Friend in Deed. It is sung by Pinkie Pie expressing her love of laughter, happiness, and friends when making her way around Ponyville with a great big smile. In the sequence Pinkie can be seen greeting several ponies, cheering up sad fillies and helping Applejack paint her barn. By the end of the song a large crowd of smiling background ponies and the leading characters have gathered around Pinkie Pie. They all sing along for the finale of the song after which Pinkie Pie meets Cranky Doodle Donkey for the first time. The song was uploaded to YouTube by user "Veronica Dela Cruz" on 7 November 2011 but removed soon after; the leak led to Hasbro "cracking down" on material released by the show's artists.[3]"
