Pinkie Pie is close with her family, be it her immediate relatives or her honorary one. A not-too-recent visit from her immediate family, as well as her discovery of being related to Applejack, have given her even more reasons to be close, and to be joyful. But when she discovers the family record of her new friend Quiver Quill, she goes off to discover whether or not they have a relative in Ponyville in the hopes of sharing that joy with them. But she soon gets a reminder that there's more than one way to have a family.
