Mia lands next to the igloo at the North Horn, where she left Centopia the last time. Mia, Yuko, Mo, and Onchao say farewell to the bluebardos and head off to the secret island.

Equipped with the petals of the fiery flower, the friends and Varia set off to the North Horn. Rixel got a tip from his spy Varia and follows them.

Mia and her friends plan to set off to the icy North Horn to find Ono, but Raynor tells them that they have to protect themselves against the cold. In Centopia’s volcano, they find the unique fiery flower to help protect them.

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.
