The Three Musketeers is an American Saturday morning cartoon produced by Hanna-Barbera Productions for NBC.
It premiered in 1968, running for 18 episodes as a segment on The Banana Splits Adventure Hour.
The cartoon is based on the 1844 novel The Three Musketeers by Alexandre Dumas.
The musketeers are sometimes assisted by a queen's handmaid named Lady Constance Bonacieux (voiced by Julie Bennett) and her young nephew Tooly (voiced by Teddy Eccles).
Tooley, who has a white horse, named Lightning, does get a present from the Musketeers, a mule for his birthday.
