Archibald Maclaren has attributed kobold behaviour to the virtue of the homeowners; a virtuous house has a productive and helpful kobold; a vice-filled one has a malicious and mischievous pest. If the hosts give up those things to which the kobold objects, the spirit ceases its annoying behaviour. Heinzelmann punished vices; for example, when the secretary of Hudenmühlen was sleeping with the chamber maid, the kobold interrupted a sexual encounter and hit the secretary with a broom handle. King Goldemar revealed the secret transgressions of clergymen, much to their chagrin. Joseph Snowe has related the tale of a kobold at Alte Burg: When two students slept in the mill in which the creature lived, one of them ate the offering of food the miller had left the kobold. The student who had left the meal alone felt the kobold's touch as "gentle and soothing", but the one who had eaten its food felt that "the fingers of the hand were pointed with poisoned arrowheads, or fanged with fire." Even friendly kobolds are rarely completely good, and house kobolds may do mischief for no particular reason. They hide things, push people over when they bend to pick something up, and make noise at night to keep people awake. The kobold Hödekin of Hildesheim roamed the walls of the castle at night, forcing the watch to be constantly vigilant. A kobold in a fishermen's house in Köpenick on the Wendish Spree reportedly moved sleeping fishermen so that their heads and toes lined up. King Goldemar enjoyed strumming the harp and playing dice. One of Heinzelmann's pranks was to pinch drunken men to make them start fights with their companions. Heinzelmann liked his lord's two daughters and scared away their suitors so that the women never married.
