The Whale Ornament is a unique item that the player obtains on Nineball Island. It is found on the beach by the bonfire, under a sparkling patch by the water. After getting this item, the player is able to encounter the Ancient Mother in the North Coast of Canada area. This item functions similarly to the Caiman Relic in that it summons a legendary creature upon its recovery.
Once obtained, the Whale Ornament is permanently inside of the player's bag, under the 'key items' heading. Its in-game description reads: "A popular souvenir from Pelago, often bought by tourists heading home."
