Three childminders are sitting round a sand-pit under a leafy tree. They have looked after all sorts of children: sniffers, fussers, sneaky and bad tempered ones. But Mrs Mackle claims she had the very worst child of all. The others cant believe it. What did Susan Solly do that was so terrible? Mrs Mackle reluctantly tells the tale of Susan Sollys strange relationship with SNAILS. The final straw came when she invited them into the house to watch their favourite TV programme, Snail Show. As Mrs Mackles tale unfolds she begins to get very agitated. But someone else hidden in the tree above, is enjoying this naughty story about herself!
