Derivable…Welcome to the “UnderWorld” bundle. When combined this set offers a wickedly hot room with animated demons! Fight, defend and run from these evil monsters. This is a room. It’s filled with fire, lava and rock. There is a cavern and then another section for you to enjoy. Inside both are dragons. One is a ride the other attacks when you click on the dangling chains. There are poses in all of the cages and plenty of room to add products.
