Answer:
I am not going to write the paragraph for you because that would be cheating. The most I could do Is give you advice.
Step-by-step explanation:
For your second paragraph, I would dedicate that whole paragraph to the "mega fish." I would capItalize that too (Megafish). Describe its outside its scales its teeth. But wait, a "Megafish" is a real thing. If you are talking about a mythical creature then you have to change the name. If not continue. Talk about rumors that you heard from other people or the old man in the rocking chair by the lake who said something real creepy to you both hinting about the "Megafish" but overlooked what you heard. Something like that. Stories need very described things. The reader needs to make the image in their head and it's hard to do that when there is no description.
