Bobby and The Gigantic Bird

Bobby was playing football outside and saw a beanstalk, so he went inside and there was a bag labelled "nothing" so Bobby opened it. It was a weird looking potion, so he drank it, he felt stronger and stronger as he walked outside. He saw that at the top was a golden egg but he could not get up, he jumped as if he could fly and soon he did! His mum and dad came outside as he started they gasped. He flew to the top and landed. He got the egg but a gargantuan bird ran after him! Did Bobby survive or not?
