There was a plan. At the beginning, there was a brave plan to make a fairy garden. The plan fell apart was when it was discovered that no one knew how to make a fairy garden. This, like all plan's pitfalls, ultimately led to the project's abandonment.
Despite their lack of knowledge in the field of fairy garden building, the intrepid trio plunged into the back yard with a passion only teenage girls can muster. (Rhinos, incidentally, happen to be just as enthusiastic in their endeavors to do... rhino... ish... things. Oh gee. The point is, Our girls here have the determination to rival a herd of strong willed rhinos.)
