Was Arnold the pig on "Green Acres"featured in?

Was Arnold the pig on "Green Acres"featured in?The reason I ask this,is because SOME people think that Arnold the pig was the star of "Green Acres".He wasn't.He was a SUPPORTING character.

According to IMDB.com Arnold appeared in 15 episodes of Green Acres. Obviously he was a supporting character. Eddie Albert and Eva Gabor were the stars of the show.

Over the run of the show's many seasons, he appeared in far more than 15 eps -- though not central to the plot of most of the episodes. As he wasn't formally listed in the closing credits to my knowledge, the number at IMDb is very low as far as documenting every and any appearance (including cameos).

Today IMDB is saying Arnold was in 66 episodes, but even that seems a bit low. That's 11 appearances per season on average. Like biffbronson said several of his episodes were cameos so it may be hard to come up with an exact number.
