Wendell T. Wolf or The Kiwi?

Wikpedia's page for Taz-Mania pointed out that although Wendell T. Wolf is mentioned as a main character in the opening, he only made few appearances, with long gaps between them. However, I seem to recall that the Kiwi didn't appear very often, either, so which of these two really did appear less?

Actually, it wasn't untill I saw Wikpedia's Taz-Mania page that I remembered Wendell not appearing very often. I wonder what Wikpedia means by mentioning him a s amain character in the opening. I think that the opening mentioned every character (with the exception of Willie Wombat, who I think appeared in the second season). Sure, Wendell was the first non-family member shown, but I don't think the lyrics said anything about a main character.
