The name is unclear due to ambiguous Polish declension and using all caps in the whole sentences in the comics. The sentence "WSKAŻ MI DROGĘ W GÓRY HERTCHU" could be translated both as "Show me the way to the mountains of Hertch" or "Show me the way to the Hertchu Mountains".
However, the phrase is most probably an Easter egg referring to Funky Koval, another comic series of Parowski and Polch duet, where the sentence "tymczasem w górach Hertchu" ("meanwhile in the mountains of Hertch") is said to be an allusion to Harz, mountain range in the Northern Germany. Since the genitive case of Harz in Polish is "Harzu", in this article it is assumed that "Hertchu" is genitive case of "Hertch".
- The name Harz derives from the Middle High German word Hardt or Hart, meaning "hill forest".
