Sam Wiggle helps children with their numeracy skills in Dr Knickerbocker as he counts up to number nine. Troy Cassar-Daley, country music star lends his guitar and vocal chords as he joins The Wiggles to sing Old Dan Tucker. The Wiggles, with the help of Captain Feathersword, help out in educating children about sun safety, such as wearing a hat and protective clothing outdoors. They are then joined by Henry the Octopus to help out with teaching children about ownership.
