Yes, that's it, Shampoo is Violet, the rest of the cast goes:

Charlie Kuno: The blue thunder of baseball.
Sally Kuno:  His sister, goes "Ha Ha Ha Ha!"  Whenever she sees:
Linus Tendo: "I am not your sweet baboo!"
Lucy Tendo: His money grubbing sister, makes money off of Charlie's
   psychoses.  Usually charges more than five cents.
Pat Kuonji:  Charlie's best friend, has a secret.
Marcie Kurenai:  Annoys Pat by calling "him" sir.

And then of course there is always that mysterious red-headed girl...

ROTFL!
I don't know that I'd actually want to *see* this done, but the idea is
hilarious.
