помогите сделать перевод текста "Fraser ,the Christmas Dragon" 2 часть пожалуйста умоляю (((((((((((((((((((((((((((((((((( даю 99 балов
Rabbie, the raccoon, was snoozing in one of the ancient oak trees. The dragon nearly bumped into a branch with his horns! "Whew, that was close," he frowned. "I’d have woken him up and then it wouldn’t have been a surprise." He took Rabbie’s package out of his big brown bag and put it in a hole in the trunk of the tree, near Rabbie’s paw. "Hee, hee, hee. When he wakes up, he’ll see his sweets right away." He tiptoed quietly into the woods, giggling the whole time.
Harry, the hedgehog, was curled up in a ball under a bush. The sharp claws on Fraser’s huge feet nearly crunched him as he walked through the woods. "Oops! I almost didn’t see Harry sleeping down there." He bent over and heard Harry snoring. "Hee, hee, hee. I’ll just set the package down right here in the bush and when he wakes up, he’ll see his sweets." Fraser took the package out of his big brown bag, put it down in the bush and then crept away.
He had one more package in his big brown bag and went walking through Thistleberry Glen, looking for Gillian, the grouse. Gillian was in her nest, curled up. Her brown and black feathers were tucked away nicely under her body to keep her warm. She heard the noise of snapping twigs and opened her eyes. Coming towards her was a huge, black shape. "What’s that?" she gulped. Just then she saw that it was Fraser. "Och, no! It’s the purple dragon that lives in the cave? Is he coming to eat me? What should I do?" she whimpered softly. She was too afraid to move, incase the dragon saw her. She sat frozen with fear in her nest as Fraser came closer and closer. She saw him take something out of a bag. "What’s he doing?" she mumbled. His big hand with sharp claws moved towards her. "He’s going to smash me and rip me to shreds with his claws!" she sobbed, but was surprised when Fraser put a lovely package down on the ground next to her nest. He was giggling and tiptoed away. "What was that all about?" she wondered.
She climbed out of her nest and picked up the package. She took a sniff of it. "That smells lovely," she said. Gillian pulled the ribbon and took the wrapping off. "Why, the big dragon has made me some sweets." She read the tag that was attached to the package. ‘Ho! Ho! Ho! Merry Christmas! Here are some sweets from your secret friend!’ "Well, isn’t that nice of him. Maybe he’s not such a bad, scary dragon after all.
Fraser crept back to his cave and curled up in the corner. Water dripped from the ceiling and he shivered all night long.-
