The Dink Network

: Thank you for your help. I have another question (i'm just a question-filled guy eh?): in the duck cave (on the 2nd island) there is a note that you can only read as a duck. I missed it and didn't run into it until after I turned back into Dink. Later in the game, there are multiple people hinting towards it holding a secret. Is there a way to get back into the cave later on in the game, or must I start a new game to read what it says? Is it another secret that is unlocked?

If it's just a message telling you something important, can someone please tell me what it says?

You need to find a duck shrine on odvi. Spacebar on it and that should be enough to get you down there.
