Go Snails Go!
Nick, Sally and the Cat have been invited along on a snail expedition! They jump into the Thingamajigger and shrink down to meet up with Lewis and Clark, the two snails leading the way! As they travel through the forest of Slippity - Goo, having fun sliding in their own makeshift shells, the kids learn about all the different ways snails use their shells.
