Caillou, the Prince of Imagination, is the subject of this free set of coloring pages. The bald four-year-old boy is sketched here in unique forms and postures. A few pages capture him having fun with sister Rosie. He can also be seen decorating a Christmas tree with her. Fans of the TV series know that she has red hair and wears a blue dress with red socks and shoes. One of the printable pages showcases him with his mom, dad and sister in his house at 17 Pine Street. The house can be colored typically in blue and the Christmas decorations would look lovely in kaleidoscopic shades. The page that depicts Caillou upside down on the fonts of his name would surely win a lot of kiddie hearts along with teaching them how to spell his peculiar name correctly. As children might already know, the dreamer a wears a yellow tee with blue pants.
