Rock Plug



Rock Plugs are rare ores that are only dropped by Boomgrocks. These items look like the top of the Boomgrock, which is a yellow cuboid (Rectangular Prism) rock. Rock plugs are really rare to find giving that these grocks are easily defeated when they are on rails and have a tendency to explode during battle.

Trivia

 * The theory behind the rarity of Rock Plugs is maybe that when the Boomgrock starts to explode, the plug is shot out in a large distance far away.
