Random Story I wrote for Biology Homework in Year 7

Okay, to everyone who will somehow stumble across this. This is an extremely INCOMPLETE story which I wrote in year 7, for biology homework. In other words, it sucks. I myself read it again and tried not to laugh, it didn't make sense in SO many areas. But hey, I was in year 7. Cut me some slack. Yes, that's the excuse I will roll with whenever someone points out how much it sucks. Anyway, you will probably see the obvious pointers to what I was supposed to include in the story. Eg. Parasitism, Food Webs, Ecosystems, etc.
Point is, read the story. The story which just kind of....stops. I'm going to publish it all in one part, so read and tell me whether or not I should consider rewriting it, if the plot is even halfway decent. Actually, if the plot isn't halfway decent it's not rewriting......
Tell me what you think!!!!!!!
