Hahaha... Here's a tip, release them into the fields and let them go wild (and eat each other). Jokes aside, this is an essay that demands a story rather than facts. Therefore its best to begin with a flow chart (google it up if you don't know what that looks like). Here's a sample plot:
Mr. Wolf was a good Samaritan, he loves his neighbours -> The goats were wild beasts who could not hold back their blood lust and their desire to devour -> One day, the goats were hungry -> They caught wind of the wolf going to visit his grandmother -> They hid themselves between the bushes lining the path to the wolf's grandmothers house -> The wolf went down the path without suspecting anything -> The goats ambushed the wolf. They then roasted him and proceeded to eat him. -> The wolf met his grandmother up in heaven. ~ Don't use my storyline, teachers and examiners hate negative stories. Plan something more cheerful instead :3
For the first paragraph, you should be introducing the characters and the setting of the story. Refer to info highlighting the characters of the story. Then refer to the situation (time and place) of the story. If I used the example plot, the characters would be:
-Mr. Wolf - good Samaritan - nice - polite
-Goats - evil - carnivorous - predatory - cunning
The settings would be:
-The path to the grandmother wolf's house.
-Midday (people travel in the early mornings until dusk)
Here's a simple sample of the story starting paragraph (notice the use of alliterations):
Mr. Wolf, a member of the canidae family, ancestors of the dogs, was a good Samaritan. He loved and cared much for those who lives around him. On the other hand, the goats, supposedly herbivorous, were savage brutes who cunningly hunted down for meat from those who lives around them. Ding dong went the bell of Mr. Wolf's house. A seemingly innocent goat was standing in front of the door, in his hand a telegram intended for Mr. Wolf. The telegram was from Mr. Wolf's grandmother who had fallen sick the day before. Unable to ignore it, Mr. Wolf set out on a journey to his grandmother's hut in the woods. ~ Don't copy, you will regret it.
Next, begin writing the actual story. The plot mechanisms has been laid out and the story is ready to be told. As for this part of the story, I can't actually type it out for you since it would make things far too easy. You should have about three paragraphs minimum for this part of the story. The plot I gave can be divided into exactly three parts: the goats get ready to ambush Mr. Wolf, Mr. Wolf went down the path and confronted the goats (he lost), and Mr. Wolf filled the stomachs of the goats. Always make use of speech to try and immerse the reader into your universe/story. An example of a dialogue spoken by the goats may be:
"Tee hee hee. That foolish wolf will never be able to spot us here," chuckled one of the goats with a sinister grin on his face. "He is much to naive to spot us!" ~ Feel free to make use of this line :D
Of course, don't go overboard with the dialogues.
Once you finish writing the story, you can write the conclusion of the story. For my plot it is easy. Mr. Wolf died and met his grandmother in heaven. Of course just like before, you might want to add a dialogue between Mr. Wolf and his grandmother.
