Find the Redstone

You’re Minecraft Steve and have been working hard to build the best device you can possibly make. You put on the last piece and flip the power switch, ready to be amazed.

Sadly, nothing happens. You go to the back of your machine and see a group of creepers running away with all of your redstone! 

Luckily, you know Alex has some locked away, but she’s off fighting the Enderdragon. It’s up to you to unlock her box and power up your machine!
