Catch the old photo blowing in the wind by the lighthouse,and take it to the Say Cheese shop. The owner will give you some diving gear for it. Return to Puffin Point and dive for Cap'n Salty's lost lobster trap. He will give you a lobster and the jet ski keys.
(Swim right, then go down to get the trap. You cannot run out of air on the way up.)
the tool is the lobster
You fetch the lobster trap.
You get the keys from the lobster guy. Then you ride. Jump when necessary to reach the island. Be faster than Nate!!
The crustacean in the lobster trap is a lobster. (see the related questions)
On Big Nate Island, you use a lobster (no kidding) to turn the lighthouse crank. (see the related question below)
Once. But you have to be at the lighthouse crank. Use the lobster and it will automatically complete the process.
you already get them when you get the lobster from the fisher man who needed the crab cage.
you never give the lobster to the seagul you shine the light houses light to the seagull and the lobster you give to the man
use the lobster that you can get after completing cap'n salty's quest
You get "pliers" on Big Nate Island* by using the lobster. To get the lobster, catch the photo flying around to the left of the lighthouse. Swap it for scuba gear at the photo shop, and dive to recover Cap'n Salty's lost lobster trap. *Pliers on 24 carrot island are "wire cutters". (See related question)
You don't just get the keys after you get the lobster and the scuba gear then the guy that wants it will give you the keys.
Use the lobster to crank the lighthouse light. Turning it left will scare the seagull from the school's bell tower.
