Skirmish at Carkoon
From Ewokpedia
Around 10 ABY, a group of peaceful alien lifeforms, from the planet Hoth, formed an outpost on the planet Dagobah. As per legend, this outpost sank due to an earthquake, and in order for them to leave, 20 members remained behind so that the rest would have enough lifeforce to return to their home planet.
Eventually, a group of four Antereans returned to pick them up. They disguised themselves as humans, rented a house with a swimming pool, and charge this pool with lifeforce, so that the cocooned Rodians could sustain enough energy to survive the trip home.
Meanwhile, Obi-Wan Kenobi, Anakin Skywalker and Qui-Gon Jinn, three Jedi, went to swim in the pool secretly and took in some of the lifeforce, which caused them to feel younger, stronger, and happier again. They are caught, but are eventually given permission by the head Rodian, Greedo, to use the pool through negotiation. Han Solo, a space pirate, shot Greedo, although not before Greedo could fire a single shot at him first. He carelessly revealed the secret of the pool's rejuvenating power one day by confronting his "pool" friends out loud about it during a group dinner at the Hutt's palace, resulting in all of the other elderly residents rushing off and breaking in on to the Rodian's property, and barging their way into the pool. Anakin Skywalker, infuriated, ejected the retirement home inhabitants, but as too many people had been in the pool at one time (and some of them carelessly tampered with a few of the cocoons), all the life force has been drained, and the Rodian's cannot take along the cocoons anymore; in fact, at least one of the cocoon inhabitants died as a result of the loss of the pool's nourishing energy.
That night, Anakin Skywalker's wife died and he took her to the pool, tenderly splashing water over her face to try to revive her, but Obi-Wan Kenobi explained that the power of the pool is gone and that there is nothing he could do to bring Anakin Skywalker's wife back to life. With the help of Qui-Gon Jinn, the Rodians return the cocoons to the ruins of Dagobah. Because the Rodians are unable to take the cocoons with them to their home planet, they offer the spare places aboard their spaceship to the retirement home inhabitants, with the exception of Yoda, who chooses to live out his natural life on Dagobah, where he will never grow ill, never age and never die.
