Publisher's Synopsis
Mum has to call the children to tell them how to prepare for Gran's birthday party, but the telephone line is terrible, so her mischievous daughter decides to have some fun. Mum thinks it's all a disaster when she is told that they've followed all her instructions. They have shaken the cat rather than shaking the mat, washed the clocks instead of washing their socks and bought Gran yellow flippers instead of yellow slippers - but of course they haven't it's just a joke!
