you have to get the lobster cage from the oyster beds in puffin point after you get the Scuba gear. Sorry that it's so long.
You do not play as Big Nate. He accompanies you around most of the island, and races you on the jet skis.
You get the keys from the lobster guy. Then you ride. Jump when necessary to reach the island. Be faster than Nate!!
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.)
There are no seagulls to ride on (as of yet) on a Poptropica island. Gulls appear on Big Nate Island, Ghost Story Island, and Wimpy Boardwalk.
It is on top of the lighthouse. You can see Seal Island from there. But you can't go there until you recover the lobster trap for Cap'n Salty, who will give you the keys to his Jet Skis.
You will race with Nate on the jet skis (one of the three mini-games) to the island where the map is stuck under a rock with seals on it. Get the keys by recovering Cap'n Salty's lost lobster trap. Climb the lighthouse and look through the telescope to see the "seal-saw" island to the far right. Until you look, you can't use the jet ski. (See related questions)
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.
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.
Big Nate Island was released in February, 2009, and followed by Astro Knights Island in June, 2009.The island after Big Nate island was Astro Knights island in June, 2009.
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 can see it from the telescope on top of the lighthouse : it is on a seal island just offshore. (to the far right) To get the map, you will need to race Nate on the jet skis. (Move the seals to one side of the seesaw rock to get the map out.) (see related question)
