Well the blue stone could be “Magic”, “Life”, “Time”, “Nature”, “Royalty/Leadership”, “Control”, “Mind”, “Peace”, “Chaos/Destruction”, “Matter”, “Energy”, or anything really.
The stone also has a flame inside of it. 
Like I’ve said before a bunch of times, I think the Blue Stone has some kind of elemental control, a more traditional kind of magic compared to the others. Mainly over fire and ice, but again, it’s just speculation. On a different level, the blue stone is able to change things on a physical (ice) and chemical (fire) level.
War is destruction, Spirit is preservation, Tech is creation, and I think the blue one is transmutation/transformation/change. If that’s what the creators were going for, that is. Someone with control over these things could have control over reality itself.
Hmm…I never thought of Time. Though it would be hard to balance that without making a complete paradox cluster****. lol
It’s nice that we can speculate anytime what the blue stone can do.
On that note, a brief theory that i had, but have failed to put much thought into yet, was that the Blue stone was the stone of Willpower.
So, srebak, you’re calling the blue stone the Will Stone.
MarianaTCdreams - The name pretty much was the theory, I’ve got nothing
Daremonger - I’ve got nothing else on the subject
People have all these explanations/speculations on what the third stone is. Since we clearly have absolutely no idea what it is, I’m calling it the poop stone until we get confirmation on the real name.
Will power/Will sounds like an interesting idea.
The stones symbolizing the code of Thundera would have been interesting but doesn’t fit the ones they actually used.
Nope. Poop stone.
You guys should just ask Dan Norton for an answer.
We have asked Dan, and he’s still not giving out details. Not yet anyway.
All Dan will say right now is that one day he’s gonna explain everything publicly in one place so that he doesn’t have to keep repeating it. But He’s just started a new job recently so I think his focus is on that atm.
Perhaps you should contact one of the shows writers then.
NOOO! I must know about teh POOP STONE!!!1!!!111!!! :mad:
Okay, that just made my day! 
Hammy0294 just made a funny. xD
As much candyfruit as they ate throughout their adventures they all had to have been good in that department.
