Artful Penny could indeed draw anything she wanted with her magic crayon and it would spring into life. A fantastically useful toy to have. Only her best friend friend Dennis knew her secret so the two had acres of fun winding up adults nosey-parkers bullies bad guys teachers and ne'er-do-wells with her creations or solving problems for folk or sketching their way out of tricky situations. Penny would scribble away her arm becoming a blurr as she worked and then - hey presto! - her line drawing would leap off the drawing surface as a fully-formed 3D object.
