Once you discover under your house that LeBorgne is responsible for stealing your ancestors' treasures, you can go back to the library on Principal Island and talk to the sailor Grobbo about LeBorgne and he will tell you about the treasure and the steps to get there.
As soon as you arrive on Proxima Island, you must activate the DISCREET mode and follow the steps to reach the Maritime Museum and in the middle of the way, you will find a Sphero who will give you the coffee pot and ask you to deliver it to Lanktir, a Grobbo who gives you access to the Mecha-Penguin room.

Note that the Sphero won't appear if Twinsen has already finished the burglary of the museum or ran up to it.
