Some of the older Sinterklaas songs make mention of naughty children being put in Zwarte Piet's bag and being taken back to Spain. This part of the legend refers to the times that the Moors raided the European coasts, and as far as Iceland, to abduct the local people into slavery. This quality can be found in other companions of Saint Nicholas such as Krampus and Père Fouettard.[9] In modern versions of the Sinterklaas feast, however, Zwarte Piet no longer carries the roe and children are no longer told that they will be taken back to Spain in Zwarte Piet's bag if they have been naughty.
