Mia meets Yuko and Mo at the Unicorn Meadow, where Onchao is playing with Esko and the other foals. Mia’s Oracle indicates that the fourth Ring might be in Panthea’s Palace.

When Mia lands in the elven crater, she notices that today is the day when each elf has a gift for his best friend. Because no one has a present for Xolana, Mo gives her the one he actually had prepared for Yuko.

An otter named Scrobbit steals one of the rings and escapes via the waterfall. Our heroes chase him to Polytheus’ island, and Mia demands that the otter return the ring of Polytheus.

The Oracle tells our heroes they should look for the next ring in the stars. Simo shows them a spot in the forest where they can watch the stars, but the night sky is cloudy. Tessandra tells them to go into the desert instead.

Mia, Yuko, and Mo leave for the Unicorn Meadow to pick up Onchao. Mia interprets the Oracle as telling them to go to the Windy Cliffs to start their search for the four Rings. They don’t notice Gargona spying on them.

When Mia arrives in Centopia, she has to learn that Onchao is missing. He had an argument with his mother Lyria about his father Ono and wanted to look after him.

Following Rixel’s last attack, Mia decides that she needs to find out more about the black oil. Phuddle wants to help, but placing the oil in his hands is too dangerous!

With a device procured from Polytheus, Rixel manipulates the animals in the crater to make them show him the secret tunnel. Mia and her friends have to master the chaos that the hypnotized animals cause in the Elf Crater.
