 File:Water Stone BW135.png
The Water Stone debuted in *The Battling Eevee Brothers* as part of a collection held by the Eevee brothers.

In *Once in a Mawile*, a Water Stone belonging to Samantha appeared; Brock's Lombre used it to evolve into Template:TP. This is the first time that a main character's Pokémon evolved via an Evolution stone onscreen.

Template:An gave a Water Stone to a wild Lombre in *A Faux Oak Finish!* so that it could evolve into Ludicolo.

In *Last Call — First Round!*, Ursula used a Water Stone and a Fire Stone during the Performance Stage of the Sinnoh Grand Festival to evolve her two Eevee, evolving them into a Vaporeon and Flareon, respectively.

*Mystery on a Deserted Island!* featured the Water Stone along with all of the other Evolution stones available as of Generation V.

A full set of Evolution stones was seen on display in a stone shop in Geosenge Town in *The Cave of Trials!*.

## In the manga

### In The Electric Tale of Pikachu manga

 File:Evolutionary stones EToP.png
The focus of the chapter *To Evolve or Not to Evolve, That Is the Question!* was Evolution stones. Template:An hoped to buy a Water Stone for her Template:TP in Stone Town, a town on Dream Island where all the Evolution stones in the Pokémon world come from. However, she couldn't afford one, remarking that an inexpensive one might make the evolution go bad.

Misty was later given a Water Stone by Mikey, who was being pressured to join the "Knights of the E Stone", a club which requires members to own a Pokémon evolved by an Evolution stone.

#### Template:Chap

In *Buzz Off, Electabuzz!*, Red's Poliwhirl was able to evolve into a Poliwrath with the help of a Water Stone when they were thrown into the water in Template:Ci Harbor, although the cause of his evolution wasn't revealed until the Template:Chap.

#### Template:Chap

In *The Kindest Tentacruel*, the Pokémon Fan Club Chairman told Template:Adv about a legend of an underwater dome at the bottom of Vermilion Harbor, housing a set of Evolution stones which, unlike normal stones, did not disappear after making a Pokémon evolve, allowing them to be used repeatedly. The cause of Template:Adv's Poliwhirl's evolution had been one of these said stones, proving the legend to be true. Yellow was later led to the dome by a wild Tentacruel, finding a Leaf Stone in it, but the Fire, Thunder, and Water Stones were missing. Later, it was revealed that Template:Adv had given them to Red so he could freely evolve and devolve his Eevee.

#### Template:Chap

In *Mowing Down Ludicolo*, Shelly used a Water Stone to evolve her Lombre into a Ludicolo while battling against Template:Adv's Pokémon.

#### Template:Chap

In *Triple Threat*, Cilan, Chili, and Cress used a Leaf Stone, Fire Stone, and Water Stone to evolve their Template:TP, Template:TP, and Template:TP into Simisage, Simisear, and Simipour, respectively, during their battle against the Shadow Triad.

## Trivia

* Through Template:DL in the Generation I games, Pokémon that would normally require an Evolution stone to evolve can be evolved without it, provided that the Pokémon levels up in the battle and the player has sent out a specific Pokémon in the same battle. In the case of the Water Stone, this Pokémon is Onix.
* In Pokémon: Let's Go, Eevee!, if the player tries to give their Template:Ga Eevee a Water Stone, they will not accept it, and therefore, will not evolve. The same thing will happen if the player attempts to give them a Fire Stone or a Thunder Stone.
