The answers are : Tygra, Panthro and “The Mossland Monster”.
:tygra: :panthro:
My Question: In spite of the title to this episode, this isn’t a Thunderan weapon. Who is the owner? What title is it? How did he come to Third Earth?
Hachiman, The Thunder Cutter, and Mumm-Ra summoned him?
This one is easy! The warned one was Tygra, by Panthro, in “Mossland Monster”.
ETA: Ok, Lady Ocelly already answered it 
Yes and its your turn. 
Update: At this rate, we could create a Thundercats version of Trivial Pursuit. 
Hah couldnt see why not. I have the Lord Of The Rings one and its a blast. A thundercats one would be great!
In what episode did a spider wrap its web around Mumm-Ra’s casket and who sent the spider in to do that?
snarf
snarf takes up the challenge
That would be correct.
name all the main snarfs to have a role in the thundercat series?
Snarf, Snarfer, Oswald, and Eggbert. Did I miss any?
That seems right to me CodeofThundera and I’m looking forward to your question.
In what episode was Wilykit knocked unconscious that Lion-O lifted her up and carried her in his arms? Who attacked her?
Merged Post:
What? No takers? If it helps, it was a spaceboard crash. And when Panthro and Tygra ran over while Lion-O was holding a now conscious Wilykit, all they could ask was about who attacked, they didn’t seem interested if Wilykit was ok or not.
What can I say? It’s a very challenging question.
Okay, much bigger hint…
It is ingrained within an episode where the story is not complete in just one episode.
Okay, I’m going to sleep on it and hopefully wake up with the answer.
Ah ha! Your last clue jogged my memory. It’s Mumm-Ra Lives! Part 2, when Lion-O encounters TugMug for the first time. The Kittens arrive on the scene first, and Kit gets injured. I don’t remember how they crash, though…
Yep, you got it!
I think it was Tug Mug’s cannon.
Ah it was that 5 part episode.
My turn?
What two locations on Third Earth are guarded by gargoyles that come to life?
Hmmm… I know one: the Tower of Traps. The other, I’m still thinking.
