Button eyes all the way! He got kinda creepy with the regular eyelids. Actually, I'm watching the series on DVD for the first time. I remember watching it when it was first on but didn't remember any of it. But yeah, I just watched the first episode on the second disc and saw he had regular eyelid eyes so I had to go to the last episode on the first disc to see what his eye status was. They were the button. I think I did the button more.
