First go to the great Wall of China then go to the wall`s right, there you will find an old dude who will challenge you for the necklace. The challenge is a memory game by the way. Then if you beat the memory game he will give you the necklace. Go to the Lewis and Clark expidition the go to the first person you see and click on the bubble that says "I have the Peace Medal" and you will have fixed that time. I would know because i beat this island and the Mythology island.
In time tangled island.
Use the swing thing to move the platform near the peace medal.
if the peace medal is not there try going on to another one of the time thingies on the clock thing because that has never happened to me
If it is not on the hook then something has gone very wrong.
The silver Peace Medal found at Leonardo's time (1516 AD) goes to the Lewis and Clark expedition at 1805 AD (8 o'clock on the time device).
The peace medal on time tangled island is on Leonardo Davinci's part of the island when you climb to the top of the waterfall and walk over to this mechanism and you will see it hanging there.
The silver Peace Medal goes to Sacajawea, but actually to Meriwether Lewis of the Lewis and Clark expedition at 1805 AD (8 o'clock on the time device).
The peace medal found at Leonardo Da Vinci's workshop (4 o'clock 1516 AD) goes to Lewis and Clark (8 o'clock, 1805 AD).
You take the note book to Leonardo, don't forget to retrieve the peace medal from under the bridge thing either.
In the future.
At Time Tangled Island, at Leo's shop, you have to jump up on the furthest wood slate at the top. Then, jump down, and go on the furthest one wood slate on the bottom. Then, you have to jump and get the "Peace Medal". By the way, it is a medal. Finally, go to the "Lewis and Clark" Time Island, click on Lewis and give him the medal
