As you sail, you discover an island with a unique shape. Dock to find out if the villagers have any clues. Since islands are far apart in this area, anyone sailing with a vehicle less equipped than the Sub-C has to stop here for supplies.
Tunacola
Tunacola is a small fishing village with friendly residents. If they have seen anything out of the ordinary, they tell you. A few of the Tunacolans are among the oldest people on the island.
The Belly of a Whale
As you travel eastward, a Whale swallows the Sub-C. You heard that they grew big around here, but this is ridiculous!
Baboo! Dr. J’s assistant is the C-Islander who was searching for you. While you were in Miracola, he was swallowed by this Whale.
This place is a maze, but nothing an experienced adventurer like Mike can’t handle.
Baboo dropped a Lighter somewhere in the Whale. With it, you can light a fire and force the Whale to sneeze you out. Search for it.
Reach the Lighter by heading north as far as you can, then heading west. Wrap around south until you reach the spot shown in the screenshot above. Push through the wall here, head south until you dock, then head east, and the Lighter is yours!
