Magical necklaces with a golden shell; given to the twins by the Seafoam Spirit to protect them from the Thornbush Pit. In The Wishing Spell, Alex and Conner need to go to the Thornbush Pit to retrieve the Little Mermaid's dagger for the Wishing Spell. The Seafoam Spirit gives them magic necklaces so the vines will not attack them. The magic necklaces work, but when they have found the dagger and want to climb out of the pit, Conner's necklace breaks and the vines start attacking him and Alex. They are saved by Froggy.
