Steaming Cerberus Tongue can't be found on gold boxes. But the triggers to pop Amarok do. Just need to kill Amarok and get KI from it. But no, Steaming cerb tongue doesn't drop from gold box, neither does venomous hydra fang.
I obtained my Steaming Cerberus Tongue from a Gold Chest before I even knew what it was.
Check it out for yourself.
As far as Heroes of Abyssea NMs that are popped with a single key item, only the ones that have key items that are obtained from a single, roaming NM can also have theirs found in Gold Pyxides. This means that for Heroes NMs, it's only
Amphitrite - KI comes from Melo Melo
Azdaja - KI comes from Deelgeed
Resheph - KI comes from Awahondo
Isgebind - KI comes from Kur
Bennu - KI comes from Ouzelum
Dragua - KI comes from Hazhdiha
Between exp parties since the Heroes release as well as solo farming in my spare time, I've seen several Gold Pyxides with KI for those six NMs in them, but I've never once seen the key items for Alfard, Orthrus, or Apademak in any of them. I've seen the others to the point that I've probably wasted a dozen or so pops of Bennu alone just because I didn't have anyone else to take the Resplendent Roc Quill when I was soloing in Altepa.
If it were possible to get the KI for Alfard, Orthrus, or Apademak from Gold Pyxides, I know I'd probably have seen at least one of those from a chest.
