We’ve broken down how trainers can go about evolving Happiny into Chansey in Pokemon Legends: Arceus.
Trainers who know of Chansey and Blissey likely know of their pre-evolved “baby” form, Happiny. Introduced in Generation IV, Happiny was originally discovered in the Sinnoh region—so it makes sense it would reappear as a part of the Hisuian PokeDex.
In Pokemon Legends: Arceus, Happiny can be found in the Oreburrow Tunnel in the Obsidian Fieldlands, Hideaway Bay in the Cobalt Coastlands, and Avalanche Slopes in the Alabaster Icelands.
How to Evolve Happiny into Chansey
To evolve Happiny, trainers will need to have access to an Oval Stone. In-depth methods to obtain and Oval Stone can be found in our Evolutionary Item Guide. However, for reader convenience, we’ll simply say that the easiest way to get one is by visiting the Trading Post in Jubilife Village.
Once they have an Oval Stone, trainers simply need to give it to their Happiny and keep the Pokemon in their party during the day. As they go about their adventure, Happiny will level up alongside the trainer’s other Pokemon, and it will eventually become eligible for evolution.
It will evolve as long as its holding an Oval Stone and leveling up during the day.
Conveniently, Happiny may already be holding an Oval Stone upon capture. It tends to carry these items to imitate its evolved form, Chansey. According to its PokeDex description, in stark contrast to Drifloon, another Pokemon that is often seen in the company of children, Happiny is often spotted “playing house” with them “for fun.” Its Hisuian PokeDex number is #086.
