Helga Blabs It All / Harold the Butcher - S3-E1
Corrected entry: The dental hygenist's hair changes color from red to brown.
Arnold Betrays Iggy / Helga and the Nanny - S3-E10
Corrected entry: In Helga's dream, her slippers start out pink, but when Inge goes after the pigeon, they're white.
Correction: It's her dream, not real. Helga can change whatever she wants in two seconds in her dreams.
Correction: No, it's auburn. Auburn hair has red highlights in it, so sometimes it looks red sometimes it looks brown.
