Synopsis
The Professor has been using a measuring stick in the Lagoon and feels that the Island is Sinking! Can the castaways build a ark/raft before its too late?

Trivia

 * One of the more sillier funny episodes - such as Mr. Howell actually having to do physical labor, when Gilligan and the Skipper test out the hut/raft before it collapses and when Gilligan reveals that was he who had changed the stick in the water for his lobster traps.
 * The Professor shows poor geological knowledge by not noticing the stick he was using was actually being moved.
 * In Rescue from Gillgan's Island, the castaways do make a hut/raft to survive a storm and end up inadvertently escaping the Island.
