Water is a chemical substance that is the main constituent of the Pacific Ocean. It can also be treated as a beverage if purified for consumption. It appears in every episode of the series, but first appears in "Reef Blower" in individuality and "Tea at the Treedome" as a drink.


Water is a transparent, occasionally blue fluid liquid. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds.

Role in series

Water appears in every episode of the series and especially plays a vital role in helping the residents of Bikini Bottom and the Pacific Ocean in general stay alive, as they would dehydrate if the ocean's water was removed in favor of pure oxygen.

There exist water helmets to assist sea creatures in breathing while in Sandy's treedome, an air-polluted dome residence in Bikini Bottom in which Sandy Cheeks lives. Sandy herself regularly wears a helmet and astronaut suit when outside in order to survive since she is a mammal.

"Tea at the Treedome"

SpongeBob enters Sandy's treedome and immediately dehydrates due to the lack of water in the environment. He tries to absorb all the water in Birdy's bath fountain only to be pushed away by him. Sandy then puts the flowers SpongeBob bought her in a vase of ice-cold water while she prepares the tea and cookies. SpongeBob eyes the vase and continuously tries to convince himself that he doesn't need the water, taking Patrick's advice to stick his pinkie finger out as a symbol of strength, but the temptations start to weigh heavily on him before SpongeBob gives up and ultimately drinks all the water out of the vase, declaring himself a quitter. Patrick runs in to restore his strength, only for him too to dehydrate in the treedome.

Once Sandy is finished making the tea and cookies, she reacts frightened upon seeing a shriveled-up sponge and starfish on the ground. To compensate, she creates water helmets for the duo to help them breathe while in her treedome, serving them their tea through the helmets as well.
