Legends tell of slighted kobolds becoming quite malevolent and vengeful, afflicting errant hosts with supernatural diseases, disfigurements, and injuries. Their pranks range from beating the servants to murdering those who insult them. One holyman visited the home of Heinzelmann and refused to accept the kobold's protests that he was a Christian. Heinzelmann threatened him, and the nobleman fled. Another nobleman refused to drink to the kobold's honour, which prompted Heinzelmann to drag the man to the ground and choke him near to death. When a kitchen servant got dirt on the kobold Hödekin and sprayed him with water each time he appeared, Hödekin asked that the boy be punished, but the steward dismissed the behaviour as a childish prank. Hodeken waited for the servant to go to sleep and then strangled him, tore him limb from limb, and threw him in a pot over the fire. The head cook rebuked the kobold for the murder, so Hodeken squeezed toad blood onto the meat being prepared for the bishop. The cook chastised the spirit for this behaviour, so Hodeken threw him over the drawbridge into the moat. According to Lüthi, these abilities reflect the fear of the people who believe in them. Thomas Keightley has attributed the feats of kobolds to "ventriloquism and the contrivances of servants and others."
