Writing About The Giant Octopus

When I went underwater for octopus hunting I could see a mantle and tentacles eating a baby shark. I stopped and watched it but it was a baby shark and it was cute. He ate it. Nom nom nom. My hands were about to throw my spear but I realised that it was a kid octopus. He was so small. My face turned white and I dropped my spear but little did I know when I dropped my spear the octopus turned red and hit me with its tentacles. I was hot even though I was underwater. When I got to my spear the octopus blended in with the rocks so I chucked my spear at the rock and got him. There was blue coming out of his body and he swam away.
