She went against Muffy in the tennis match, but Muffy's modern racket broke before they could play the 16th century version.
Buffy used a 16th-century tennis racket that (supposedly) was passed down from Henry V (her great-great-great-great-great-great uncle).
Buffy is a rabbit with a cream complexion and hair identical to Muffy's, but with white bows.
She wears the Glenbrook uniform with a white collar shirt, a dark blue tie, a plaid skirt, a light blue V-neck shirt, and a medium blue jacket bearing the Glenbrook insignia.
- She may be making up the relation to Henry V, referencing "Background Blues".
- She is unnamed in the show, but the chapter book based on the episode says her name is Buffy.
