Twirlywoos 3 сезон 16 серия — More About Fitting Together

The Twirlywoos watch a lady trying to make a picnic bench, fitting planks of wood together. Her dog comes to tell her it is time for a walk. Whilst she is away, the Twirlywoos start fitting together the planks of wood, but are they following the instructions for the picnic bench or making something completely different?
