Where to find a Sewaddle and how to evolve them
Where to Find SewaddleBefore you can evolve Swadloon into Leavanny, you must first locate its pre-evolved form, Sewaddle. In Kitakami, Sewaddle can be found in the southern area, spanning from one coast to the other. According to the Pokedex, they primarily inhabit grassy regions, so remember to search within those areas. Although Sewaddle typically evolves into Swadloon at level 20, most wild Sewaddles you encounter will already be above that level. Consequently, all you need to do is level them up once.
How to evolve Swadloon into Leavanny
Swadloon undergoes evolution into Leavanny once the required happiness level is achieved. In order to make Swadloon evolve into Leavanny, its happiness level must reach 220, and it should level up once thereafter. Although the happiness level cannot be directly seen within the game, it does not decrease over time. Therefore, the key is to engage in activities that boost the happiness level. Some of these activities include interacting with your Pokemon during a picnic, giving them EXP candy, leveling them up, and allowing them to accompany you in the world. Furthermore, having Swadloon in your party also contributes to increasing its happiness level. By undertaking these activities, the evolution from Swadloon to Leavanny can be expedited.
