Long before they met that tornado of music and joy that is Pinkamena Diane Pie, Carrot Cake and Cup Cake were merely a couple of newly-weds that opened a bakery on their hometown.
Life was pretty dull for them until the day they opened their door to meet a curios and crazy stallion who just barged in to become their assistant.
A small stand-alone story based on The Lodger episode of Doctor Who series 5.
DonĀ“t think too much of it. Is not connected to any story aside from having the Doctor on it.
