Grandad Charlie and Sam pass the time with a story about the cactus, a popular and unusual plant. A family of woodpeckers is blown into the desert by a storm and get lost. The desert becomes dry and very hot. A scorpion and a lizard tell the woodpeckers they need to find a cactus as they contain water and insects. Mother woodpecker finds a cactus and the family have a drink.
