Thanks, zax!
I agree. It is indeed strange for it to be called the Throne Room. I think the only episode in which we see something resembling a throne is “Mumm-Rana” when Mumm-Ra and Mumm-Rana are sitting on thrones in front of the sarcophagus.
Ok here’s my question:
Where is the source of the River of Despair?
In Turmagar the Tuska, Turmagar suggests that the springs in Tuskania are the source of all rivers. Then, at that end, Lion-O calls the spring they’re observing to be “the source of the river”, singular. Since the River of Despair is the only river the ThunderCats ever seem to encounter, it’s probably the river he’s referring to.
So, Tuskania?
Good reasoning!
Let’s wait for Wilycub’s veredict.
Yup, it is Tuskania indeed! Well done, zax!
You’re turn, sir.
So, Zax, are you there?
He said he was getting married on the 31st, he could still be on his honeymoon.
As I have several stored in the back of my head, I’ll step into the breach in the meantime:
Another one about “the catchphrase”:
What was the first episode in which Lion-O used the catchphrase for a purpose OTHER than summoning the others to him? And what did it do instead?
I’m just guessing here, but was it in “All That Glitters” when he used the catchphrase to elongate the sword and then use it as a shield to block the flying rocks and debris from the exploding volcano?
Nope - it’s earlier than that.
And just to be clear - you can go with either the production order, the airdate order, or the continuity order we’ve worked out here (although it needs revising, come on people, talk to me there!) - the answer is the same whichever you use. THAT should give you some clue.
BTW - whatever ultimate purpose the catchphrase is used for, it ALWAYS elongates the sword, unless it’s already at maximum length (as it is in “The Super Power Potion” for example).
Is it the Doom Gaze? I think he used it then to retrieve the TCs from Ta-She’s spell.
Nope - it was just used as a summons in that episode, and it was only Lion-O and Snarf who were under the spell.
I’ll try another guess. Is it in “Exodus”? To awaken the Thundercats from their hypersleep? 
No - he was still using it as a summons/call for help there.
Here I am! No honeymoon, though—just negligence.
Is it in “Pumm-Ra”, when he uses it to distract and overpower the Lair’s Cats’ eyes, and then unlock the front door? Sort of prelude to the BASH button incident, if you ask me. 
I do have a new question that I can post this time, I promise!
Spot-on, sir! That was the very episode I was thinking of. He uses it to overpower the eyes, which in turn opens the door for some reason.
OK Zax - you’re up - again!
Welcome back, Zax! And congrats on getting the correct answer. I forgot that Lion-O uses the catchphrase twice in that episode, first to summon the others and then to overpower the eyes. I could only recall the first instance. 
Welcome back Zax! Congratulations on the wedding!
Thanks! Actually, he only uses it the once. It’s Pumm-Ra’s attempt to use it that summons the others—or, rather, concerns them enough to rush home.
Thank you! It was a lot of fun, a great success.
Okay, here we go.
Cats’ Lair and the Tower of Omens are both powered by generators, fueled by thundrillium, and some component of each generator is pressurized.
What should the pressure gauges at each fortress read (in psi), according to Snarf and Snarfer?
Is it 78psi at the Tower and at least 94psi for the Lair?
Samophlanges?
Lol… j/k
That’s it! From “Mumm-Ra Lives! Part II”.
You’re up, adssse.
