The Beechwood Grove Full Moon Ball is a dancing event mentioned in the first Beechwood Bunny Tale, Periwinkle at the Full Moon Ball, and its TV adaptation "Le premier bal d'Agaric." The Ball, which is held by the Wise Old Owl on an unspecified summer night, is the "best dance of the year," according to the book; all of the Bellflowers plan to go when that book's events take place.
