Sophie and Emma want to make some extra money, so Philip suggests they wash his car for money. The girls hate washing Philip's car, when their next door neighbour, Peggy, says she'll pay to have her car washed, Sophie comes up with a plan: she asks Adil to shrink the car down to the size of a toy, so they can wash them in the sink. Max says the girls can wash his car, but Adil accidentally shrinks Max's car down while Philip is inside.
