Sewer Troll

When Jester the cat is pushed down a hole by a vindictive frog, he discovers a subterranean world he never knew existed. The creatures he encounters tell him of a mysterious monster that's been using the sewers to enter people's homes through their toilets. Unfortunately, this smelly being may also be his only way out of the slimy tubes and tunnels and back to his comfortable life in the world above.
This unusual story of odd animals and curious creatures has been devised and illustrated throughout by six-year-old author Jack Sharp.
