How to Evolve Happiny

In the Pokémon games, Happiny is the baby form of one of the most well-known Pokémon in the series: Chansey. Making a Happiny evolve into a Chansey is more complex than it is to evolve most other Pokémon — unlike ordinary Pokémon, it won't simply evolve when it reaches a certain level. To get Happiny to evolve, you'll need to give it an Oval Stone, then level it up during the daytime.

Get an Oval Stone. Oval Stones are evolution-inducing items that can be given to your Pokémon for them to hold. Once your Pokémon has an Oval Stone, leveling up at the right time will make the Pokémon evolve. To get an Oval Stone, simply walk around the areas where they are found. When your character walks on the correct square of floor (which is assigned at random), a message prompt with “Your character has found an Oval Stone" will appear. Below, find the locations in each game where you can find Oval Stones:^{[1]XResearch source}
- Diamond/Pearl/Platinum: Lost Tower; the Underground; found on wild Happiny and Chansey
- Heart Gold/SoulSilver: Rock Tunnel; Bug Catching Contest (first prize); Amity Meadow; found on wild Chansey
- Black/White: Challenger's Cave; Black City shop B; during Dust Clouds; found on wild Happiny
- Black 2/White 2: Dust clouds inside the Relic Passage, Rebirth Mountain, and Clay Tunnel; White Forest
- X/Y: Unknown Dungeon (hidden on a rock to the left of Mewtwo); PokéMileage Club (balloon popping, level 2)
- Omega Ruby/Alpha Sapphire: Found on wild Happiny
- Sun/Moon: Paniola Ranch; "Path for Brilliant-Stone Hunting!" mission of Isle Aphun in Poké Pelago (available starting at Rank 2)

If you don't already have a Happiny, get one. Happiny is available in all games from Generation IV onwards. It doesn't matter which level the Happiny you catch is — with the Oval Stone method, you can evolve one at any level. Below, find the locations in each game where you can find Happiny:^{[2]XResearch source}
- Diamond/Pearl: Trophy Garden; hatch the egg from the trainer in Hearthome City
- Platinum: Trophy Garden
- HeartGold/SoulSilver: Breed Chansey or Blissey equipped with a Luck Incense
- Black: Trade only
- White: White Forest
- Black 2/White 2: Hatch the egg from the trainer in Nacrene Gate
- X/Y: Breed Chansey or Blissey equipped with a Luck Incense
- Omega Ruby/Alpha Sapphire: Mirage Forest, Mirage Mountain
- Sun/Moon: Route 1, Route 4, Route 5, Route 6, Hau'oli City, Lush Jungle (only available by being called as an ally Pokémon in all cases)

Wait for daytime to arrive. Happiny will only evolve into Chansey in the daytime. From the fourth generation of Pokémon games onward (which also happen to be the games that Happiny is available in), the in-game time is the same as the time on your device's clock (and thus the real-world time if your clock is accurate.) Note that the Pokémon definition for "daytime" varies from game to game. See below for more information on each generation's "daytime":^{[3]XResearch source}
- Generation IV (Diamond/Pearl/Platinum/HeartGold/SoulSilver): 10:00 AM-7:59 PM
- Generation V (Black/White/Black 2/White 2):
  - Spring: 10:00 AM-4:59 PM
  - Summer: 9:00 AM-6:59 PM
  - Autumn: 10:00 AM-5:59 PM
  - Winter: 11:00 AM-4:59 PM
- Generation VI (X/Y/Omega Ruby/Alpha Sapphire): 11:00 AM - 5:59 PM
- Generation VII (Sun/Moon): 6:00 AM - 6:00 PM (Sun), 6:00 PM - 6:00 AM (Moon, which takes place 12 hours ahead of your device's clock)

Getting Happiny to Evolve

Download Article

1
Give the Oval Stone to Happiny. Once you have an Oval Stone in your bag and a Happiny with you, you're all set! Start by opening your Bag and selecting the Oval Stone. Select “Give” from the small menu that pops up, then choose Happiny from your list of Pokémon.
- If you've done this right, message should appear on the screen telling you that Happiny is now holding the Oval Stone. Happiny will keep the Oval Stone until you give it something different or it evolves.
2
Level Happiny up once. Now, get into battles with enemy Pokémon and start winning. The precise Pokémon you fight don't matter — they can be Pokémon you find in the wild or Pokémon from an enemy trainer. As long as you win, Happiny participates in the battle, and Happiny survives until the end of the fight, it will gain experience.
- If you're in an area with many difficult Pokémon and you don't want to risk having your low-level Happiny faint, you may want to use an Exp. Share item, which allows even Pokémon that don't participate in the battle to gain experience points.^{[4]XResearch source}
- Other things that can boost the rate of experience gain include having a high affection level in Pokémon Amie (Gen VI) or Pokémon Refresh (Gen VII) and having Pass Power (Gen V) or O-Power (Gen VI) active.
3
Watch Happiny evolve. When you get Happiny enough experience points to level up, it should start to evolve immediately. Congratulations! You now have Chansey.
- Note that your Oval Stone will disappear after the evolution.
- Keep an eye on the clock as you get your Happiny experience points. If you battle long enough that your Happiny levels up during the night, it will not evolve into Chansey and you'll need to wait for daytime or adjust the clock and try again.

Question
On Pokemon Moon, how do I get shiny Solgaleo?

Top Answerer
You don't. It's one of those Pokemon that cannot be shiny, at least not until a future special event.

Question
What level does Happiny evolve?
Lugia2453
Top Answerer
It doesn't evolve at any specific level. As long as you level it up in the daytime with it holding an Oval Stone, it'll evolve at any level, as long as it's not level 100.

Question
Why can't I give Happiny the oval stone?
Community Answer
You just tap the bag, press give on the oval stone, and then select Happiny. Now level up, and you should get the Chansey.

Tips

Don't want to wait until daytime comes naturally? Try saving your game and manually changing your console’s system clock to make it come sooner.

Now that you have a Chansey, see How to Evolve Chansey for tips on reaching the next level of evolution: Blissey.

After defeating the Elite Four in Pokémon Sun, you'll be able to go through a portal at the Altar of the Sunne during the nighttime to go to an alternate world where it's daytime. This can be helpful if you prefer to play during the nighttime and want to evolve Happiny without changing the system clock. You need Solgaleo/Lunala in your party in order to do this.
Thanks
