A collab between me and SuperPinkBrony12.
Takes place during the events of A Bird In The Hoof.
On their way to give a cake to Princess Celestia due to her Royal Gathering in Ponyville, they bump into the party pony herself, Pinkie Pie. She decides to tell them a little story about her own special cooking experience. One that's hard to believe!
Glad to have worked on this with you. It feels like it could've been an actual episode of the show.
