This ancient Tableaus Temple has been opened for you to explore. Its very dangerous, so you can only send in one pet at a time and while the pet is inside the temple, you cannot trade or exchange the pet. Make sure you are prepared - the temple has many obstacles, 30 levels some say, but not many have made it all the way to the treasure deep inside! While inside the temple, your pet will notice many closed, locked doors which can only be opened by the hidden knowledge of Bug, Fish and Robot Minipets.
At each level of the Temple, you will get a prize. It can be either items, currency, pet stats or Account Upgrade Credit. There is no time limit for completing the Temple, but you can only complete one level every 12 hours. If you manage to reach level 30, you will be able to choose any Hidden Avatar you are missing from your Hidden Avatar Collection - it will be added straight to your collection for use around the site. Here is the Prize List.
