Thanks to Jonny 313 and Talior for help with this info…

Check this out, here is a picture of the finished construction at the Ninja Hideout with the secret door to the Volcano Room and a picture of the Volcano Room itself!

Heres how you will get to the Volcano Room.

There will be a Door/Portal to get to it! Here is a closer look at the door.

If you are a member ninja you will have to step through the portal/door to get to the Volcano. There is also a note on the wall of the door.
