Lil Sue has started a delivery company called Deliver Sue, and in a quest to raise money for a new set of wheels, Dave lands himself with a job - Anna thinks she knows how to deliver packages quicker than Dave, though, and a dramatic sibling rivalry soon unfolds.

Gran sits in front of the television for so long that she turns into a cocoon, and with a little help from Dave - who wants his favourite seat back - she hatches into a moth. When Moth-Gran sets her sights on the moon, it's up to the Spuds to find a way to entice her back.
