YooHoo, Pammee, Roodee and Chewoo visit a majestic cave on the Karsts. They become marveled with beauty of the miraculous underworld. The Snowy owl Loonee entertains them with many beautiful songs while they are in the cave.
YooHoo's gang reaches the Aeolian Islands after a long trip. They meet dandy Libee, who catches Pammee and Chewoo's heart with magic tricks. Libee put the seed pouch to the side with his magic and the boys blame him.
