It was found near the Bloonhenge's Great Rock after the real Omega Bloon was defeated. It is now used detect and destroy the Color Gems Dimensional Bloon created. It seems like a small gun carring a small Omega Gem, the colored parts mean the proximity of a Color Gem (from cyan to red). It is also used to obtain 50% more Omeganium from the Omega Bloon's copies. You can only equip it in a Monkey Warrior.
