What will the Fearless Five's next adventure be?

Well, my first book is well on its way to being published. Now, I must begin building and collecting ideas for my next story - the second book in the series, "The Adventures of Penelope Star." What new characters am I going to add? What are their names? What do they look like? What grand adventure will the Fearless Five go on? What mystery will they solve in that magical world of Dragon Point? My mind races at all of the possibilities. I have ideas, but now I need to pull everything together...this is where I must rely on my imagination, my creativity, and of course my wonderfully inspiring muse...
