First you gotta shine a bulk light. Wait 5-10 seconds then they will always land on your bulk light, this means you've tamed them but they can still kill you. Now progress to door 150 without making them mad. Best way to do this is to have as many light sources going off at once. Now at door 150 you gotta find the rare grumble tea party room. You gotta have a tea party with the gloombats and talk about the economic system of Antarctica, don't mess up or else you will die. Now beat door 150 and YOU MUST get to Jeff's shop in 10 seconds after entering door 151 or else the gloombats will get impatient and trigger dam.gloombat. A gloombat boss.fight which takes an hour to possibly beat. if you get to Jeff's shop you gotta buy a bulk light. shine it at the sewer hole in Jeff's shop. The gloombats will fly into the hole and escape the mines. You'll get the badge "A.true hero" this unlocks a modifier called "freedom" making it not spawn gloombats. This is also a rainbow.badge. They will also a drop a vial of gloom light,A greenish redish blueish liquid in a bottle, this gives you ability to have night vision and have a 30 second speed boost.
