Okay, no more Howdy Doody trivia! The Native American was Chief Thunderthud (Joyce, Peyton, and Michelle) and he belonged to the Ooragnak Tribe - kangaroo spelled backwards (Michelle, Peyton, and Joyce). I also know that he was the ONLY Native American to be portrayed on TV with a mustache! And the Chief coined the word, "Cowabunga" - not that annoying cartoon character in the Simpson Family!
Based on your observations, what would this structure be called. It's that simple!
