Happy Hozlidays!

I'm sure some of us remember when Fred Meyer used to send out holiday cards to the Oz Club with descriptions of unwritten Oz books on the backs.  To continue the spirit of these cards, what if we all post our own unused plot ideas?  I think a good theme will be characters introduced in the series who never got books of their own.  I'll start with:

LANGWIDERE IN OZ - When the multi-headed Princess of Ev realizes that some of her heads are starting to show signs of aging, she makes a journey across the Deadly Desert to Oz, in order to find some way of restoring their youth.  She has to make her way past various monsters and strange villages on her way to the Emerald City, not to mention the difficulty of wearing a single head for several days in a row.

Now, how about your ideas?
