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.
