A boat came to check why the lighthouse wasn't working. It saw the rats, and the crew signaled them with the light. They left, but soon returned with some other boats to help try and rescue them.
One of the boats is a barge, and inside the barge is a bunch of meat. There was also gasoline poured everywhere. They used the meat to lure the rats into the boat. When the rats got in, they lit the gasoline, and they burned all of rats. The rats that tried to escape were eaten by sharks. Itchoua, Jeff, and Le Gleo were saved.
