For my laptop, I did not like any of the worlds that I had because they were all very old, so I started a new world. I am mining some clay when night falls so I build a tower of sand to stand on top of so that I will be safe. I came to discover that I had made a rather poor choice now that there are several spiders and creepers waiting for me to go down. I may be able to escape with clay blocks as well. I also got to see the rare spider rider. Hooray.
