This is a colouring book with six changes which can be shown as you flip through the book. They are :
The entire book has blank pages
Book has nursery rhymes printed on left pages and right pages are blank
Book has nursery rhymes on left pages, and black and white illustrations on the right pages.
The black and white line drawings now have streaks of random colours
Colours are partly filled in, but all wrong (green and purple faces, blue trees etc.)
All pictures are correctly and completely "coloured in."
Although there are six possible changes, the performer need not use all six for the routine. He or she may perform a shorter routine if so desired.
