Madame Mandilip's special dolls are costumed as members of vicious street gangs known as the Apache (pronounced ah-PAHSH), who were involved in theft, prostitution, and the occasional murder in pre-World War I Paris. The dolls even perform the Apache dance popularized by the gangs, in which extremely close steps alternate with seemingly brutal punches, kicks, hair-pulling, spins, and throws; it was usually danced to the Valse des rayons (aka Valse chaloupée) composed by Jacques Offenbach. In the 1930s and 1940s, this dance was still performed by professional dancers and can be seen in several films and even cartoons of the period.
