From her oracle, Mia knows that Panthea is the only one who knows where Ono is. If the elves could bring one of those flowers Panthea dissolved into, Tessandra can try to “make the flower speak.”

The friends find the Jade Horn at the coastline of Centopia and find out to use the ring to open an access to the Rainbow Island.

Together with Mia, Violetta arrives in Centopia. She calls herself Varia and claims to be a princess from another island who has lost her memory. When Varia learns that Mia plays a central role in Centopia, she becomes jealous.

The friends have assembled the four rings. They now have the key to the Rainbow Island, but where is the lock this key fits into? They have to decypher the runes engraved into the ring.

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.
