Professor Bramble the Badger pushes a beautiful gypsy cart which he uses as his mobile class room. He and Head Mistress Miss Nutella Nutkins are on a field trip, collecting new objects for their show and tell collection.
These objects intern become part of a game of "Animal, Vegetable or Mineral?" each introduced to the children by a puppet guest lecturer. The game allows children to discover the wonders of the Natural History as they handle real fossils, minerals and other materials.
