As the sun

 As the sun came up we could see this massive cube.
It was glowing purple and there was a whole bunch of soldiers standing in front of it
They started shooting the cube but I think the bullets are either submerged in or bounced off. 
The Cube started slowly moving. It was about to crush all the soldiers.
The Cube has just landed on them. Then tanks started coming in and firing.
and then launched a missile at it.
It absolutely did nothing, the missile bounced off and went into the ocean and exploded.
The army has left. I and my friend Jack went up to it.
” Bob, you should touch it” Jack said. “No, you”. So he did. It slowly started pulling him in.
  I didn't know what to do so I  pulled on Jack's arm as hard as I could. It did nothing.
“oh no it's got me” yes I got out of it just in time before it got my whole arm.
“oh no” the army has taken me in and is now asking questions.
I’ll get back to you when I can...
