Rewrite this story to be about a sea turtle who gets tangled in a net

Once upon a time there was a shy and quiet octopus. He nearly always went about on his own because, although he wanted to have lots of friends, he was too self-conscious.

One day, the octopus was trying to catch a very slippery oyster. Before he knew it, he had tied himself into one massive knot, and he couldn't move. He tried with all his strength to wriggle free, but it was no good. In the end, despite the great embarrassment he felt at being seen in such a tangle, he had to ask for help from the passing fish. Many fish swam past, ignoring him, but one very kind little fish offered to help to untie all those tentacles from all those suckers.

The octopus felt heartily relieved when he was finally set free, but he was so shy that he didn't dare talk to the fish and make friends with him. He simply thanked the fish, and quickly swam off. Later, the octopus spent the whole night thinking that he had wasted a great opportunity to make friends with that very kind little fish.

A couple of days later the octopus was resting between some rocks, when he noticed that everyone around was hurriedly swimming past. He looked into the distance and saw an enormous fish coming over to feed in that area. The octopus quickly hid; then, peeping an eye out from his hiding place, he saw that the huge fish was chasing the kind little fish who had untied him. That little fish really needed urgent help, but the big fish was so dangerous-looking that no one dared to go near. The octopus, remembering how the little fish had helped him, felt that he had to do whatever he could to come to his aid.

Without hesitating, the octopus shot out from the rocks, like a ray. He put himself right in the path of the giant fish, and before the fish could do anything about it, the octopus had shot out the biggest jet of ink of his life. He grabbed the little fish, and swam off back to hide in the rocks. Everything happened so fast that the big fish had no time to react. However, he soon recovered from the surprise. Off he went to the rocks, looking for the octopus and the little fish. Now he really wanted to gobble them down!

Soon, though, he began feeling a terrible itch; first in his gills, and then in his fins, and then all over his body. It turned out that this giant fish had a very artistic nature, he adored colours; and the octopus's dark ink had given him a terrible allergy!!
So the big fish swam away, irritated all over.

As soon as he was gone, all the fish who had been hiding came and congratulated the octopus for being so brave. Then the little fish told them all how he had helped the octopus a few days earlier, but he had never known anyone be so grateful that they would end up doing something so dangerous. Hearing this, the other fish discovered how nice the shy octopus was, and everyone around was keen to be the friend of such a brave and honourable octopus.
Once upon a time, there was a shy and quiet sea turtle. He nearly always went about on his own because, although he wanted to have lots of friends, he was too self-conscious. 

One day, the sea turtle was trying to catch a very slippery piece of seaweed. Before he knew it, he was tangled up in a massive fishing net and he couldn’t move. He tried with all his strength to wiggle free, but it was no good, in fact, he only got more tangled.  In the end, with great embarrassment, he had no choice but to ask for help from the passing school of fish. Many passed him by, ignoring him, but finally, one small and kind fish offered to help untangle him from the net. 

The sea turtle felt so relieved when he was finally set free, but he was also shy that he didn’t dare talk to the small kind fish and try to be friends with him. He uttered a simple thank you and quickly swam away. Later on that night, the sea turtle kept thinking about how he wasted a great opportunity to finally make a friend. 

A couple of days later while the sea turtle was resting on the rocks, he noticed everyone swimming by in a hurry. He looked off into the distance and saw the largest fish he had ever seen coming to feed. The sea turtle quickly hid, while peeking out from his hiding place he saw the enormous fish chasing the small kind fish.  He knew that the small kind fish needed his help, and even though the enormous fish was dangerous-looking he felt he had to do whatever it took to help the small kind fish and return the favor. 

Without thinking, the sea turtle shot away from his hiding place. He put himself right in front of the path of the enormous fish, and before the fish could even react, he hit the hard shell of the sea fish and was stunned. Taking advantage of the enormous fish's stunned reaction the sea turtle grabbed the little kind fish and swam back to his hiding place. Everything happened so fast that the enormous fish had no time to react. Once he recovered, the enormous fish swam above the sea turtles hiding place in search of them both, with plans to gobble them up!

Soon, though, he began feeling a terrible pain in his nose, that quickly spread to his head. The hit to the massive sea turtle's shell had caused the enormous fish to get a headache. The enormous fish began to swim away giving up his search. 

As soon as the enormous fish was gone, all the other fish came out of their hiding places and thanked the sea turtle for being so courageous and brave. The little kind fish told them all how he had helped the sea turtle a few days ago and how he was grateful the sea turtle returned the favor. Once the other fish had heard the story, they discovered how shy the sea turtle was and everyone was so proud to be the new friend of such a brave sea turtle.
