First of all penumbra, you have a very interesting name which I quite love to know about. The penumbra is the excess light from a lunar/solar eclipse. Known to be 'Partial light'. The umbra on the other hand is the 'Total darkness' and is a very thin spot of the eclipse. Anywho, google is very interesting. As for zoplik, I have no clue what language you speak, but its probably just jibberish because your name is not part of the English language and I do not recall this word in any foreign language. But for your message, Roger is mine, and I will bring him into any conversation I please.
