Most of them feature some type of mob spawner and usually a chest filled with treasures. It’s a great addition for exploration in mcpe as it expands on things which you can discover. It’s also a great challenge as each structure will be guarded by hostile mobs. All different types of dungeon will generate at random in your worlds. The generation frequency is quite high which causes the structures to be spawned very often. However, some structures only spawn in certain biomes, e.g. the igloo in snow biomes and so on.
