Lego The Hobbit Red Brick Guide

All collectible red bricks can be found by completing a fetch quest for someone in the HUB world. You must find a character that is willing to give you a red brick in exchange for a Mithril item. To get their requested item you will need to locate the Blacksmith Design and then craft the item at the Blacksmiths workshop in Bree. Once you have crafted the item you can return and exchange it for a brick. Once a brick has been bought you can then turn it on by accessing the Extras menu.
