Which of these was a henchman for Witchiepoo in the U.S. TV series "H.R. Pufnstuf"?

"H.R. Pufnstuf" is a children's television series produced by Sid and Marty Krofft in the United States. It was the first Krofft live-action, life-sized-puppet program. The seventeen episodes were originally broadcast from September 6, 1969, to December 27, 1969. The broadcasts were successful enough that NBC kept it on the Saturday morning schedule until August 1972.

The show centered on a shipwrecked boy named Jimmy, played by teenage actor Jack Wild. He is 11 years old when he arrives on the island and turns 12 in the episode called "The Birthday Party". Jimmy and a talking flute named Freddy take a ride on a mysterious boat, but the boat was actually owned by a wicked witch named Wilhelmina W. Witchiepoo (played by Billie Hayes) who rode on a broomstick-vehicle called the Vroom Broom.

Orson Vulture (performed by Joy Campbell, voiced by Lennie Weinrib) is a stuffy, somewhat inept vulture who is one of Witchiepoo's henchmen. As her favorite flunky, he multitasks as her sounding board, butler, and co-pilot on her Vroom Broom. Orson once made the mistake of asking what the W. in his boss' name stood for. The answer: WHACK!
