Bob notices that the yard needs tidying and the driveway needs fixing. He asks Dizzy to stay behind with Scratch to do this important job. Scratch is worried about being at the yard without Bob - but Bob eases his mind by putting Dizzy in charge. It's a big responsibility; Dizzy will be like Scratch's big sister! Scratch is very excited to have a big sister and Dizzy is very excited to be a big sister. At first, their tasks go well, but Dizzy and Scratch soon discover that they share a sense of humour and fun, and joking around begins to take the place of being responsible. Enjoying being a fun big sister so much, Dizzy fails to guide Scratch in his work. It's only when he makes a huge mistake that Dizzy realizes how she has let Scratch down. As he panics, Dizzy finally takes responsibility and calms Scratch down. She shows him how they can work together to fix the mess before Bob and the team return. Job done, big sister!
