Build a spy bunker, watch two pens all night, then light up the Kingdom.
Night falls. Something is moaning outside your walls… Time to find out where monsters come from.
- New skill Using light to control mob spawning
- Level 2 · Rise of the Kingdom

- Mode Survival
- Time 35–45 min
- Ages 13+
What you’ll build
Before sunset, fence two matching pens: one lit with torches and one left pitch dark. Build a sealed spy bunker with glass windows nearby and watch both pens through the night, tallying every mob. At sunrise, use what you learned to light up the dark spots in your Kingdom.
Finish line: You've watched both pens all night from your bunker, and your Kingdom is lit up to keep monsters away.
Bonus challenge: Run the spy mission again on a second night. Same result? What does that tell you about trusting just one night?
You’ll need
- Fences
- Torches
- Sand for glass
- Blocks for the bunker
You choose
- My bunker's codename
- My bet: which pen fills with monsters?
- The darkest corner of my Kingdom
Stuck?
- Seeing no mobs at all? Check the difficulty isn't Peaceful, where monsters don't spawn.
- Seal the bunker completely and light it inside so nothing spawns in there with you.
- Mob numbers change a lot from night to night, so note anything odd rather than expecting a perfect result.
