When Alex and Conner try to gather the magical items they need to make the Wishing Spell work, one "ingredient" is the dagger the Little Mermaid got from the Sea Witch to kill the man she loved. "A saber from the deepest sea, meant for a groom's mortality." It was already used by the twins' father and disposed of in the Thornbush Pit. The Seafoam Spirit tells them where to find it and asks them to destroy it after they use it for the spell. After the battle with the Evil Queen, the dagger is destroyed in the fire of a guestroom of Snow White's castle.
