Up in Spout Hall the hot weather is having an effect on the inhabitants. Fenella is even more cross than usual and her telescope, Riley, is drooping so much she cannot see what the Wheelies are up to. Down in Wheelie World all of the Wheelies have gathered in the square as there is a problem. Wheelies need a regular supply of sarsaparilla or they will seize up, but the hot weather has dried up the sarsaparilla stream. They have got to go to the sarsaparilla fields to drill for more. Fenella sends her toadies out to spy on them and when she hears what has happened she is determined to stop them. Claptrap gives her a spell that will make their drills useless but Chorlton and Fenella's gigantic son Clifford put their foot in it - quite literally.
