Posie Flump is bored and wants to play but all of the other Flumps are busy doing things. When she asks what they are doing they tell her but tell her it is a secret and to 'keep it under your hat' - but Posie is not wearing a hat.

Pootle is making a mess in the house looking for mislaid bits and bobs. So, Ma Flump gives him a pocket to put things in. Pa Flump gives him a strong magnet but soon he is coated in metal objects and falls asleep.
