12-year-old Jakob helps out at his mother's vegetable stand and also carries customers' purchased goods home. One day, an old woman with a long nose comes to the stand and claims that the herbs are bad and were better 50 years ago.

"Don't you like it, my beautiful long nose?" the woman scoffs, "You should have one too, even longer than mine." Finally, she buys some cabbages, which she wants Jakob to carry home for her. Jakob resists but is persuaded by his mother. Other market women whisper whether the old woman is not the evil fairy Kräuterweis.
