Underworld Portal is the Toy Pad Build in the Venture Halloween Story Pack.


The Underworld Portal is a manufactured structure which acts as a gateway between the Over World and Underworld. An Underworld Portal is built as a rectangular frame of obsidian (4×5 meters minimum, 23×23 meters maximum). The four corners of the frame are not required, but portals created by the game will always include them. The obsidian can be placed in any manner, e.g. by placing mined obsidian or by casting it in place using lava and water. Adjacent Underworld Portals can share obsidian blocks.

Once a frame is constructed, it is activated by fire placed inside the frame. This creates portal objects inside the frame, resembling a tornado. The fire can be placed in any manner, including use of fire steel or a fire charge, impact of Espouse plasma, or natural spread of fire to flammable material adjacent to the portal. Portals are created in the other dimension when the player uses one.


  • It is based on the Portal Hallway from Robert's Abode, specifically the Underworld Portal (as the name implies).
  • Amongst the items scattered on the floor are a diamond blade, a giant metallic axe, a diamond mattock, a wood spade, and a woody pitchfork.
    • In addition, there are stacks of books (including a magical one), potion bottles, a wine pitcher, and a treasure chest.
  • It is one of few religious references in LEGO Dimensions (the others being demons in Gauntlet and the "Red Demon Brick Smash" ability).
    • As such, the name was changed in some regions:
      • In Arabia, it is known as the بوابة المطه, or Portal of Disinfectant.
      • In Hebrew, it is know as the פורטל העולם התחתון, or The Underworld Portal.
      • In Tamil, it is known as the பாதாள உலக வலைதளம், or Underworld World Web Site.
