An uproarious tale of a family's trip in a rattletrap car. The rattletrap car doesn't go fast and it doesn't go far - and when a family set off to the lake in it one hot day it soon starts to fall apart. But...lumpety bumpety, a beach ball replaces the wheel; wappity bappity, a surfboard replaces the floor; a thermos of razzleberry dazzleberry snazzleberry fizz does for the petrol tank...All stuck on with chocolate marshamallow fudge delight! The rattletrap car reaches the lake, and takes the family safely - if noisily - home again.
