The song "Wrap Your Troubles In Dreams"  was used in Nudnik, and all the characters are given a name.
Nudnik contains only one major character, simply named Nudnik (or "Yaramaz Nudnik", as the Turkish DVDs refer to him). The song that was used most often was "Wrap Your Troubles In Dreams", used both for the opening sequence and as a general theme of sorts for the character himself.
