Some of you have caught hints of them earlier, but now here they are! Molly, Polly, and Holly: the three kid sisters of Ally Herman.

In stark contrast to Ally as an overgrown bodybuilder, each sister can be described as follows:

Molly, the rude and rebelious one. She plays for an underground Roller Derby team and skates anywhere she wishes with little regard for authority. While hot-tempered, she does know what's right for herself and her friends.

Polly, the quiet and wise one. She likes to meditate and perform yoga excercises. She seeks peace within conflicts between others, especially between Molly and...

Holly, the impatient, yet punctual one. She likes to jog, run track, hurdle, vault, and race. When not participating in said activites, she sets out to accomplish many, many little things on her long agenda. Thoroughly and swiftly.

Despite their differences, the sisters all act as a team. In fact, because Holly gets all fidgety and tense and talks so fast, it annoys Molly. Fortunately, Polly calmly makes peace between the two, maintaining their sororal bonds with each other.

And when that doesn't work, their mother Allison steps in to exert her authority over her daughters.
