The Captain’s Quarters. Requirement: Scanner (Quest Item) & 6 specific "Rusty Keys." This is a scavenger hunt within a scavenger hunt. The Abandoned Ship has six hidden keys (in trash cans, under beds, inside broken lockers). Unlike the vanilla game where the scanner gives you a TM, in Hyper Emerald 5.5, the scanner plus all six keys opens a safe behind the captain’s portrait. Inside is the Rusted Crown . Equip this to a Tinkaton to evolve it into Tinkaton Lord (Steel/Fairy, base stat total 600).
