How could i improve my story telling skills?

One upon a time there was a magic baby called Libby, she was 22 feet tall and had seven arms on her face, and had 20 legs and feet she had vampire teeth and big green eyes.Libby lived in a magical forest where the magical animals came from. she was evil to people that is why she is so big she eats 20 tonnes a day. but also she does lots of charity work for the children. The other day she did a sponsered run and raised £4.50 so all the children could share a large fish and chips for their tea. Her best friend was Dave the magical wonder pony.But Dave had a deep dark secret. The secret is that in fact he is not a pony but is really a horse called Gary who works at KFC. Everyday Gary gets some beans,gravy,chicken and chips from the KFC and gives it to the children. Because Libby the magic baby was a bad baby she attacked Gary and stole all the food apart from the beans. When gary had recovered from the attack he carried on along on his journey home to see the children. He told his mum what happend and she said she will tell Libby off . Gary gave the children the beans, but they all shouted," we don't want no beans!!" Gary was so upset by this that he turned evil and joined forces with Libby attacking KFC delivery workers. All of a sudden a there was a funny sound and a bright sparkley rainbow came down from the sky.A mushroom king came down from the rainbow he said to go on a quest to find a GOLDEN KEY TO A DOOR. Libby and Gary killed some more KFC workers then set off on their quest. To get the key they would have to travel far away to the furry mountains of mouldy cheese and go and see Richard the mountain tramp. But because it was friday Libby's mum said she could not go out untill three o'clock next year on tuesday.
