Walkthrough
As you complete The Terrible Titans... Lurking Locked Away Adventure, you will have to go through a number of various areas across the Crown Tundra in search of the Regi Legendary Pokemon Group. One of these areas is the Iron Ruins found at the start of the Giant's Bed, which is where one of the Regi Legends can be found. In order to open the door to the ruins, you must whistle in front of it. The Regi found within this temple is none other than Registeel, and it can be battled by lighting up the tiles on the ground and clicking on the statue afterwards.
Interactable Pokemon
