This has got to be the most ingenious and funny “Topic” since this game started. 
Nice one, Zax! 
I’m glad you think so! Now we just need someone to post a fifth answer. I have a whole bunch that I can share once the topic is closed.

Thanks for posting the rest of Ma-Mutt’s nicknames, “Zax”. Who would have thought that Mumm-Ra had such an extensive vocabulary? Must come from solving all those crossword puzzles for thousands of years before the Thundercats arrived and gave him something else to do!

4. Wiz-Ra’s Helmet
I thought about Wizz-Ra’s helmet, but wasn’t sure they specifically said it was made out of gold, so thank you for solving it out for me, Liam
Mumm-Ra refers to it as the Golden Helmet of Phar-Nur. Gold it is!
One of the reasons I chose this question was because of Panthro’s unusual claim that gold was a “strange Third Earth metal”, and that there was nothing like it on Thundera. So weird.
This quote does not make sense later in the series when the golden oar is presented to the guardian in the last episode.
