Understanding the process to evolve Happiny into Chansey is essential for trainers seeking this nurturing companion. While this adorable pink egg Pokémon captivates trainers, transforming it enhances battle readiness. Follow these steps to unlock Chansey’s potential.
Happiny’s Habitat
Before evolution, securing this Pokémon is crucial. Easily captured with a standard Pokéball, Happiny appears in:
- Sword/Shield DLC – Multiple zones including Challenge Beach, Fields of Honor, and Forest of Focus
- Legends: Arceus – Mass outbreaks at Horseshoe Plains, Obsidian Falls, and Avalanche Slopes
- BDSP – Hatched from Hearthome City’s gifted egg or found in Trophy Garden
- Scarlet/Violet – Various provinces including South Area Three and West Area One
Evolution Mechanics
Daytime leveling with an Oval Stone triggers Chansey’s transformation. Legends: Arceus simplifies this by requiring only the held item.
Oval Stone Acquisition
This critical evolution item appears in multiple Switch titles:
- SwSh – Hidden in Soothing Wetlands or Courageous Cavern
- Legends: Arceus – Available at Jubilife’s Trading Post
- BDSP – Grand Underground discoveries
- SV – Casseroya Lake or Levincia-area Pokémon drops
Post-Scarlet/Violet updates simplify breeding—female Chansey naturally produce Happiny eggs without Luck Incense.
Chansey’s Advancement
