Location: In the Overworld, travel to the southwest beach that leads to the Ruined Atoll and go to the little island just off the shore. You'll need to have page 1 of the instruction manual in order to find this secret treasure and use a hint from page 51 as well.
After 60 seconds open the instruction manual to page 1 and you'll see a new drawing appear on the bottom right of the page, indicating where you will find the secret treasure chest, along with a secret message that serves as instructions.
This one can be a little tricky - you can find a hint for what to do on page 53 of the manual but basically you'll need to have the Magic Wand, the Magic Dagger and the Magic Orb equipped. Target the slime and use both the Magic Wand and the Magic dagger at the same time to attack it. When it has frozen over, use the Magic Orb to hook yourself up to the ledge. Kill the slime to get it out of the way and the secret treasure will be all yours.
You can find hints for this puzzle on pages 28 and 34 of the instruction manual. Pay attention to the windchime hanging outside of the Old House. It plays a song and pauses before it repeats the melody again. The notes are in sets of two, rising and falling, sometimes at the same time or sometimes they're both the same note. There is a musical key for this song on page 34 on the bottom left corner of the page. Once you've figured it out, enter the code using the D-pad. 041b061a72
