Children enjoy decorating large Halloween coloring books because it occupies their imagination during a festive occasion. There is a sense among young ones that Halloween is an adventure filled with candy and spooky monsters. Seeing such monsters in an easy-to-use coloring book is a treat for them when they are already in-the-moment. They have an opportunity to paint creatures like mummies and ghouls in their own fashion, with their own rules. It makes them think of the costume they'd like to wear on the day, be artistic, and stay absorbed with curiosity about the fanciful images on the printed page.
