Pat has a very unusual delivery - an enormous tree which Alf has ordered for Thompson Ground. Pat has strapped it into the four-by-four and is driving very slowly. Jess is worried about the little nest Pat has not noticed in the tree - it's full of baby birds!
The children have an archaeological dig in Thompson Ground too, as Alf thinks they will have fun digging whilst he digs a hole for his new tree. The children find a few treasures and finally Pat delivers the tree and the nest full of baby birds all safe and sound.
