Ocean monuments are one of the five randomly created constructions that lack a treasure chest (including fossils, swamp huts, desert wells, and nether fossils). They can only be found by using debug commands on the ocean floor. The best way to find treasure inside an underwater temple is with the help of robots. There are three robots available in the game: Ada, her son Alex; and E.V.A., their virtual assistant. To make things easier, all robots have a tendency to go to locations with high treasure values. You can program them to search specific areas by using the debug command. There are nine different types of treasure you can find inside underwater temples. Some of them are hidden behind blocks or require certain equipment to retrieve it, so use your imagination and try to figure out how to get those treasures! Gold coins: As long as you have battery power left, you can keep finding gold coins. It's easy money! Silver coins: Same as gold coins except they're silver instead.
