Buffy

Buffy is a student of Glenbrook Academy in Mr. Pryce-Jones' 3rd grade class, and a lookalike of Muffy Crosswire. Her first and only appearance so far was in "The Return of the King".

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).

Physical appearance
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.
