Two anime titles

[Sammy Boy]

Hello,

I am wondering if anyone has ever watched the Gold Lightan:

or the anime version / extension of the Wizard of Oz:

I saw them when I was 4 and 6, respectively. I really enjoyed them but don't remember much about them, except that the Gold Lightan and his robot friends could go from really small boxes to really big robots.
