Strange Mobs

Chapter 1: The Beginning
Here's one thing about me. I. Love. Minecraft. So, when this happened, I was pretty freaked out.

My friend and I were playing on my realm, and we had built this huge city. It had tons of cool things like restaurants, hotels, and a church. We were playing a survival role playing game on there, when suddenly it turned to night. My friend and I thought it was pretty weird, because the sun was still rising when it happened. But we thought it was jus a glitch, and we continued playing. Later on, we saw a weird creature. We were sprinting through the Farmer's Market and we saw what looked like a pig. When we got closer, we thought it was a pink spider. I asked my friend if she had downloaded any mods, and she said no. We paid it no more attention, and we went to sleep. But an unsettling thought was creeping into my head...

Chapter 2: Noises
It had been 5 days since I last logged on to our realm, and when I finally did it again something was definitely wrong. Our buildings were burning down, and the fire wouldn't stop spreading even though it was raining. There were also odd mob noises. Then, I remembered the strange Pig Spider. Horror dawned on me. I called my friend, but she wouldn't pick up. Then, one of the mobs attacked me. It looked like an Enderman Creeper from my view. I was about to die when i saw the flash of an enchanted diamond sword. It sliced the mob in half, and standing in the monster dust and XP was my friend. Here's how our chat went:

 Thanks.

 You're welcome. What was that thing?

 I don't know. It looked like an Enderman Creeper.

 Hmmm...

 Do you have food? I'm at half a heart and I only have 6 bars left.

 Ok

Then, we logged off again. But I could still here the noises in my head.

Chapter 3: Again
We made plans to log on again the following Saturday, to investigate the weird mobs. When we logged on, the same thing happened again. It turned to night. More strange noises. We were used to it by now, so we weren't as freaked out.
