Mysterious Laboratory

Mysterious Laboratory is an underground location present in the third season of 12 oz. Mouse. This Laboratory is shown to be an underground cavern underneath Lotharganin. The Mysterious Laboratory is inhabited by Aria, Professor Wilx, and eventually Mouse Fitzgerald. This Laboratory has a monitor set, a security and defense system, an outdated prototype known as T.O.P.A.Z., alarms, and blipping robots.

During the events of "Adrift", The Eye traveled on a boat through Lotharganin's oceans to this laboratory to meet up with Fitz and co. in "You Made This." The Eye also shows them some shadow puppets on a stage play. In "Because They Could", Aria, Fitz, and The Eye go to a room full of weapons such as various guns to take out a hoard of Bow-tie Bots.

During the events of "Reveal", Professor Wilx traps Fitz, The Eye, and Aria in a laser cage before escaping the Laboratory. Eventually, in "Prime Time Nursery Rhyme", Golden Joe and Peanut Cop end up in this Laboratory. The latter of which gets killed by a bomb on the ground after freeing Fitz, Aria, and The Eye from the laser cage by pressing a switch in "Here We Come."
