The series is based on the books written and illustrated by Ed McLachlan, one of Britain's most beloved cartoonists and illustrators.

Simon in the Land of Chalk Drawings follows the adventures of a six-year-old boy with a vivid imagination and a particularly exciting talent: everything he draws comes to life! Simon simply climbs a ladder, and jumps over the fence into the Land of Chalk Drawings - a colourful world of his own creation. In this world, the sun and moon may argue over equal time or a tornado may be transformed into a harmless kite. Whatever the adventure, it's Simon and his magic chalk to the rescue!
