Challenge Story 4 Random Words Chosen By You

So since this is my first one I’ll ask my mum for 4 words they are. Octopus, Crane,Scissors and Obsidian.

There once was a octopus that lived down in the depths of Atlantica, a place unknown for thousands of years but no octopus lives in peace. One day whilst the octopus was cleaning its neighbouring shells a big metal shard came crashing down. Scissors, loads of them, a whole box. They came down like daggers and unfortunately that was the end of one of his tentacles that was cut off by one sharp piece. Now once falling daggers are rusty old sea garbage. Still no peace. One day when the octopus was exploring new territory a massive crane came crashing down, suddenly ripping off 2 tentacles and breaking the octopuses home below. Peace?Never. This time the octopus was just swimming around Atlantica when suddenly loads of rocks, including obsidian came plummeting down from the above thousands of shards were charging straight at this octopus, people didnt realise their garbage the seas killer. The octopus was hopeless, a shard of Obsidian went straight through its head killing it instantly.
