on top of the lighthouse at puffun point
you have to look all the way to the right
You go to the telescope where the guy is painting, look through the telescope and you can get on the jets now!!
Climb the lighthouse and ask the artist if you can look. (Once you see the seals on Seal-Saw Island, you can race Nate there on the jet skis.)
You don't use the boat on Big Nate island. When you have recovered Cap'n Salty's lost lobster trap, he will give you the keys to his jet ski. Look through the telescope atop the lighthouse to see where you are headed. You also have to outrace Nate.
Look through the telescope on top of the lighthouse to see where you are going : the seal rock has a map under it. Race Nate to the island to get the map.
All you have to do is in these 2 steps 1.Look through the telescope until you find a map 2.click on ride on the jet and your having a race
You have to look through the telescope on top of the lighthouse to see where you are racing to, which is the island with the seals and the seesaw rock.
You do not play as Big Nate. He accompanies you around most of the island, and races you on the jet skis.
Go right then there is a light house then you go up then there is a man then you talk to him and say may i have a look?
You can't play "as" Nate, but everywhere you go on the island, he tags along.
There is no Duke among the characters of Big Nate island.
The key fits the jet ski, so you can race Nate out to the seal island to the right of the lighthouse (you can see it through the telescope). The map to the time capsule location is there. (see related question)
