Horlepiep is a traditional Dutch polka performed by bandoneon player Jan Rap. The cue is used as theme music for Mrs. Puff and/or her boating school.

This APM plays at 101 beats per minute.



  • Despite Mrs. Puff first appearing in the episode "Boating School," this APM was not used in that episode; her second appearance in "Hall Monitor" was the debut of this APM.
  • "Shanghaied" is the only episode where this track plays but neither Mrs. Puff nor her boating school appear.
