He can tell where those creepers, spiders, and skeletons are going to spawn on an intuitive level.
All we can do when we're around creepers is run as fast as we can. You'll take care of your child IRL and your technologically savvy kid can take care of you in this brave new world. It's okay, don't feel bad! Paired with multiple creeper costumes this pixelated suit is enough to put fear into the heart of even the most experienced Mine Crafter which is perfect, it's the season of the scare after all! Now, can you send your crafty kid over to help us build our cabin? How can we use those enticing planks in our inventory to build ourselves a nice, cozy cabin? Oh, and that ominous castle behind that hill, stay away from there unless you've figured out how to make a sword. That panic we feel when the sun is going down is a feeling that should only apply to real life situations but we can't help it, it's primal! Yeah, we totally had you fooled, right? Sure, it might be frustrating playing a game that your kid is great at while you're respawning left and right but at least you have someone to protect you from that angry mob of pixelated villains.
