in the ancient ruins of shark tooth island
On Shark Tooth Island, the translation key is the missing page atop the ruins. On Nabooti Island, the Sphinx symbols are all matched, not translated. (see related questions)
you have to find the paper that was torn out of the journal and look at it and spell open
There is no honey on Shark Tooth Island. The three ingredients you need are coconut milk, a creature bone, and the green Key Ingredient. (see related question)
There are two "keys" on Shark Tooth Island, neither of them a real "key" : 1) The "translation key" which is a page from Professor Hammerhead's journal. It shows how the ancient hieroglyphic symbols translate into English. Spelling out the word "OPEN" in these symbols will open the ruins door. The page is on the roof of the ruins. 2) The "key ingredient" is the green substance that make the shark sleping potion work. It is far to the left in the underground ruins. (see related questions)
