I Don't Believe My Eyes in DOORS: How to Survive Gloombats

Updated 10.10.2026· Author: Mark K

Where to get it

Hear chewing behind the door? The next room has Gloombats. Survive it, and the badge is yours. They appear in The Mines and have a chance to show up when you open a door.

How to get it

Listen for the swarm: a loud metallic buzz gives away the Gloombats.
Turn off your flashlight and any other light. Gloombats leave you alone if you don’t have an active light source.
If you really need some light, use a glowstick or Laser Pointer. They won’t anger the swarm.
Make it through the room to the next door, and you’ll earn the badge.

How hard is it?

This badge is common: about 19.6 million players have earned it, which is roughly 4 out of every 100 players who entered DOORS. The only hard part is resisting the urge to turn on your flashlight in the dark. I couldn’t do it for a long time, and it cost me health every time.

Tip

I keep my flashlight in hand, but turned off. The swarm won’t attack if the light is off, and you can turn it on as soon as the buzzing stops.

Darkness Is Your Friend Here

Most rooms with Gloombats are dark, so you’ll feel the urge to reach for a light. Don’t. Flashlights, lighters, and other light sources won’t provoke them when turned off. But if you turn on a light, the swarm will attack until the light goes out or you die.

You can turn on a light when you can no longer hear the buzzing or the swarm is far away. As long as they sense the light, they’ll follow you into the next rooms.

Mistakes That Cost You Health

I forgot to turn off my Straplight. The swarm will attack even if you’re hiding, as long as it’s on.

I stepped on the eggs. New Gloombats hatch from them. Watch where you step in dark rooms.

I forgot about the glowstick. A dropped glowstick lights the way, and the Gloombats swarm it instead of you. I think it’s the best item for this badge.

Where the Name Comes From

The name and the line about “ten million” refer to Owl City’s song “Fireflies.” It says you wouldn’t believe your eyes if you saw ten million fireflies. Fireflies do love light, though, and these creatures hate it.
