Give the characteristic features of the elf which helped Patrick.
Patrick saved a little doll from his cat. That doll was, in fact, a very small sized man, an elf. He was timid. He felt grateful to his saviour. In return, he promised to grant Patrick a wish. He could not say ‘no’ to any of Patrick’s requests. He agreed to do Patrick’s homework. But he was illiterate. He sought Patrick’s guidance at every step.
