Water Water Everywhere

Water, Water Everywhere is the 14th episode of Gilligan's Island and the 14th episode of the first season. It aired January 2, 1965.

Synopsis
The Professor has built a pedal-powered water wheel for a breadfruit garden, but while Gilligan is pedaling it, he realizes the garden isn't getting water. When he investigates, it's discovered their freshwater spring has dried up, leaving the castaways without water. Gilligan rushes to tell everyone, stopping Ginger in the middle of a shower and forgetting what he was trying to tell her, but remembering when the Skipper tries to wash the mud off him. The predicament leads to a serious rationing of fresh water. Everyone's personal water supplies are placed into a large community container, but when the Skipper suggests using a diving rod to find a fresh supply of water, the Professor scoffs at the idea until everyone discovers Mr. Howell is hoarding water in his personal ankle water flask. That night, as Gilligan is watching the community water container, both the girls and the Howells distract him to try and sneak water back, but they're both caught by the Skipper who learns Gilligan has created another diving rod. When the Skipper wants to see it, Gilligan jerks it away, puncturing the community water and leaving no water for anyone. The next morning, everyone is mad at him. The Professor and Skipper start digging a well in hopes of finding water and are so disgusted with him that they're no longer speaking to him. Meanwhile, the girls are creating a tarp to catch dew for water, and the Howells are attempting a rain dance. Feeling he's no longer appreciated, Gilligan decides to leave camp, but while writing his note, a frog jumps on to the table. Realizing its wet, Gilligan follows it into the jungle and stumbles into an underground cave filled with water. Meanwhile, Mary Ann finds his note and tells the Skipper he's missing. During a search, he finds Gilligan's hat near the cave and falls in as well, quickly apologizing to him after finding him safe. Unable to see in the cave, they ask the Howells toss them matches to light their way, but the Professor tries warning them about subterranean gases just before an explosion occurs, throwing the Skipper and Gilligan out of the cave and into a tree. At dinner, everyone celebrates over a mugful of nice fresh water, but Gilligan believes they should give credit to Froggy, his new best friend.
