The unintended consequences of Monster Eggs

[Note: It’s been a while since I have done this work on a map and these tools that I mention below may be out of date. Nonetheless this may be a good place to start if you care to try something like this yourself.]

I find that Minecraft mishaps are some of the funniest things I can ever experience, here is one such mishap:

On the various servers that I have set up for my son and his friends, I have built or edited some area of the map in order to set up some sort of adventure. I set up perhaps a castle with a mob generator in it and some treasure chests placed in a more inaccessible part. The tricky bit is to make it somewhat obvious to the players what their goal or goals are. My solution was usually to make a number of interesting things in the area and hope for the best.

A tool I use to edit maps is MCedit ( ) which works on OSX and Windows. It allows me to more or less cut and paste things into (and out of) Minecraft map files. Add on scripts which can be found with an internet search can add functions like road or castle generation.

In this particular case I chose to make a dungeon using a plugin or add on script that works with MCedit called “Dungeon schematic randomizer” ( ). This lets one make a dungeon made up of a number of set rooms that will be randomly arranged in such a way to all be connected. The result is not always satisfactory in that it often produces difficult to navigate dungeons which may frustrate players.


A less exploded part of my dungeon


I chose a room somewhat deep in the generated dungeon and made, what I thought, would be, an interesting treasure room with a puzzle that employed some redstone circuitry that would allow a hidden chest to be revealed. This was a finishing touch and although there are some puzzle rooms included in the set rooms from the the above plugin I chose to make my puzzle room myself in creative mode. Thus I went about mining out the room a bit and placing my fairly simple red stone device which was a well with a pressure plate at the bottom that was connected with redstone to a piston which would pull back to reveal the hidden chest in the floor when someone threw an item of some sort down the well. There was also a somewhat cryptic clue on a sign to encourage the kids to throw something down. In the course of building this in creative mode I decided that I wanted to discourage mining through walls to get at the treasure instead of figuring out the puzzle. So I included monster egg blocks in the blocks I set in the walls and the well. Monster egg stone blocks look like stone blocks except that they take slightly longer to mine and then release a silverfish . Silverfish will also spontaneously emerge from monster egg blocks if there is a silverfish being attacked nearby. This will be important later in the story.

So I was finally satisfied with my creation and invited my son and a friend to investigate the dungeon. They were somewhat reluctant and to encourage them I followed along in creative mode to offer advice and recover dropped items should something bad happen. Eventually, with some prompting, we arrived at the entrance to the treasure room. At this point we were jumped by some zombies and a creeper which normally wouldn’t be much trouble. However, the creeper blew up, damaging some nearby blocks and an unfortunate series of events followed.

When I was applying what I thought was a sprinkling of monster egg blocks to my creation I seem to have lost track of when I was using a regular block and when I was using the former. They look exactly the same in the slots on-screen and I used many more than I thought I had.

Fast forward to our encounter at the treasure room and the result was a cascade of silverfish emerging from blocks everywhere. I helped but every time it seemed we had them licked, a new wave came at us. When silverfish emerge from their block on their own, the block is destroyed and the treasure room began to look like Swiss cheese. They also will burrow into a block if they are not otherwise occupied and thus even more blocks were destroyed when they emerged again. The result was a hilarious, panicked session which we somehow all survived, escaping with the loot from the now exposed “secret” chest. Pictured below is what is left of the treasure room.

That was my memorable experience with map making. If you choose to try it and it is still possible even with the current version (this particular adventure occurred on a Minecraft Realm), I wish you good luck and always know where your backup file is.


Your cat + Minecraft

By way of a new post here is Mojang’s announcement of their contest to put your cat into Minecraft in a low-res sort of way:


Fame. Glory. Respect. Cats have dreamed of these things for millennia, but recently to little success. Whatever happened to the excellent PR team they had during the Ancient Egypt era? These days, a cat has to look angry in a YouTube video to get a solid career going. Humiliating.

But no more! Because today we’re announcing a contest which gives you the opportunity to get your cat in Minecraft! Our excellent pixel artist, Jasper Boestra, has already designed loads of cute-tacular new cat skins that are coming to the game. But he was too lazy/untalented to make the final one. So that’s where YOU come in!

Minecraft’s top 10 bugs


From the site:

Minecraft is a notoriously stable and precision-crafted game. Everyone knows this. However, on the rarest of rare occasions, a tired developer’s finger slips on their keyboard, or someone drops their cinnamon bun into the Central Flux Capacitor, or we forget to make the timely sacrifice to Omak’katheth, and the game wigs out completely. Sorry about that.

But it doesn’t always turn out badly: many of Minecraft’s most infamous errors were, in hindsight, happy accidents, that led the way to new features and even new mobs.

And so, in memory of those fleeting moments of instability and/or serendipity, we asked the developers to recall their favourite bugs and glitches from across Minecraft’s history and its many platforms.

Excerpt from Mojang’s: “Minecraft Guide to Exploration”


Essential tips from the forthcoming Guide to Exploration

The following how-to is an exclusive excerpt from the Minecraft Guide to Exploration. Along with the all new Minecraft Guide to Creative, it’ll be released tomorrow on May 30th in the US and June 1st in the UK. You can pre-order the book here.

When you first spawn it’s a race against time to gather resources before night falls and the hostile mobs come looking for you. Every adventure is different but this step-by- step guide is one option that will keep you safe until day two.

  1. Mark your spawn point with a dirt pillar, and/or note the coordinates.
  2. Find some trees and hit them with your hands to collect 20 wood blocks.
  3. Drag the wood into your crafting grid to turn it into wood planks.
  4. Make a crafting table from 4 wood planks and place it on the ground.



I recommend Mojang’s first set of Minecraft books: Minecraft: Essential HandbookMinecraft: Redstone Handbook, Minecraft: Combat Handbook, and Minecraft: Construction Handbook. These are available separately or as a set.

Minecraft sickness

From Minemum:

  • Why does Minecraft make me seasick?

    A lot of people get motion sickness when playing 3D games like Minecraft, and vertigo and headaches can also cause problems. Playing in third personand turning off the head bobbing can sometimes help. Some other things that might work are changing eye focus away from the screen regularly, not playing in fullscreen, increasing the frame-rate, taking regular breaks, turning down the display brightness and playing in a well-lit room.
