Treasure the China Bird was the beloved pet of Fernando Bullforth. She disappeared shortly before Valanice arrived in Falderal, ending up in the possession of the Snake Oil Salesman who kept the little bird in a cage. Valanice found the frightened bird in the cage. The queen assured Treasure she was a friend of Fernando's and brought the little bird back to her owner. In thanks, Fernando gave Valanice a china mask.
Treasure appears in King's Quest VII: The Princeless Bride, as an objective for Valanice to find. Completing this task gives the player the china mask that proves very important a short while later.
