Since the original phrase seems to have adult - related connotations, in a family - friendly version, we could consider it as a story of changing from one symbol or element to another. For example, in a fairy - tale - like story, a magic spell might change a 'dildo - like' object (but not in the sexual sense, more like a unique - shaped object) to a 'cock - like' object (again, not sexual, like a rooster - related object) as part of a magical adventure.
Well, without the sexual implications, it could be a creative story where there is a swap or switch between two things that are named in a rather strange way. Maybe it's about two characters in a story who have these unique items, and through some kind of magic or adventure, they exchange or transform these items in a way that teaches a valuable lesson about change and adaptation.
