The Pink Fairy Book
“ The lad thought so too while he swam round the palace and peeped in from every side. ‘Here, indeed, it would be better to be a man than such a poor dumb fish as I am now,’ said he to himself; ‘if I could only remember the words that the troll says when he changes my shape, then perhaps I could help myself to become a man again.’ He swam and he pondered and he thought over this until he remembered the sound of what the troll said, and then he tried to say it himself. ”
