Periwinkle at the Full Moon Ball (French: Le premier bal d'Agaric Passiflore) is the first book in the Beechwood Bunny Tales series.

[3] A young rabbit named Periwinkle Bellflower ("Agaric Passiflore" in the French version) learns of the summertime Full Moon Ball that will soon take place in the community of Beechwood Grove.

But, with the help of a conniving magpie, Magda, and a wood pigeon and a frog as his teachers, he soon learns how to do so in a couple of days.

On the night of the Ball, Periwinkle takes centre stage with his moves, unaware of Madga's plan: the whole of Beechwood is supposed to laugh at him in embarrassment.

On November 10, 2004,[4] France's TF1 network aired an adaptation of the book, entitled "Periwinkle's First Dance" in English.
