Domestic kobolds are linked to a specific household. Some legends claim that every house has a resident kobold, regardless of its owners' desires or needs. The means by which a kobold enters a new home vary from tale to tale. One tradition claims that the kobold enters the household by announcing itself at night by strewing wood chips about the house and putting dirt or cow manure in the milk cans. If the master of the house leaves the wood chips and drinks the soiled milk, the kobold takes up residence. The kobold Heinzelmann of Hundermühlen Castle arrived in 1584 and announced himself by knocking and making other sounds. Should someone take pity on a kobold in the form of a cold, wet creature and take it inside to warm it, the spirit takes up residence there. A tradition from Perleberg in northern Germany says that a homeowner must follow specific instructions to lure a kobold to his house. He must go on St John's Day between noon and one o'clock, into the forest. When he finds an anthill with a bird on it, he must say a certain phrase, which causes the bird to transform into a small person. The figure then leaps into a bag carried by the homeowner, and he can then transfer the kobold to his home. Even if servants come and go, the kobold stays.
