We had just arrived. Dib and Zim were going at it again. Nobody really seemed to care, as usual. I did, but I said nothing. The teachers had gone away, maybe they died. We sure wouldn't care if they did. I think maybe they left the island. No one paid them any attention. No one ever did anyway. There was beeping noise and then that's when I noticed the loudspeaker. That's when everyone noticed.
Someone (some teacher or something) announced, "As you may see, Zim and Dib are setting an example for all of you. I would advise you all to do the same or I will take you off the Earth myself. Find the tree marked with an X. Then there will be weapons to choose from. Then, once everyone finds a weapon, a bell will sound and you may begin the fight. The last few standing will gain power unimaginable."
I had figured that I would sit and wait it out; but that wasn't the case.
