The Bomb Shelter is a decoration which is available to all players at Level 30 or over. It costs $5600 to purchase and its dimensions are 2x3. It is the second of two Level 30 decorations, following the Training Dummy. Although the Miniature Nuclear Warhead was also released with the Level 30 update, it is premium and therefore does not require the player to reach Level 30 in order to purchase it. It is most likely based on the bomb shelter Herman Hermann shows Homer Simpson in Treehouse of Horror VIII.
