Production
The book's author is credited as "A. K. Yearling", the fictional pseudonym of Daring Do, but is actually written by regular My Little Pony chapter book author G. M. Berrow.

The book is bundled in the Adventure Collection with Daring Do and the Eternal Flower, Daring Do and the Forbidden City of Clouds, a cardboard replica of the book that hid the Ring of Destiny in Daring Don't, a gold-painted miniature Daring Do figurine, and a cardboard treasure chest that houses the entire collection.
