Undella Town (Japanese: サザナミタウンSazanami Town) is a town in the east of the Unova region. To the south of Undella Town is Route 14.
Sinnoh champion Cynthia rents a villa in Undella Town. She can be battled once regardless of the season, and can afterwards be battled once a day during spring. The female Gym Leaders and Elite Four members will often visit her during the Summer and Spring, respectively.
Outside of Summer, this town has very few people and almost looked deserted, the villas are all empty. But during the Summer season, the villas in the town are occupied by vacationists who is on a leave from work. One of the vacationists stated that he came there from the faraway region of Hoenn. Undella town's sea is the peoples' favorite when summer.
Unlike some other towns, where singular instrument tracks are added to the background theme in certain circumstances, Undella Town has two different themes depending on the season. In summer, a lively calypso tune is used; in autumn, winter, and spring, a mellow synth-led arrangement is used.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Upon visiting Undella Town, the player will see Draco outside The Riches' Villa. After accepting his challenge and defeating him in battle, he will show the player inside, then tell the player to come back the next day. If he or she does, and defeats Draco again, Susan will enter the Villa and immediately challenge the player. Doing this the next day will cause Clairdonna to appear, then Zillion, and so on. After defeating Miles, the family will not accept any more challenges.
Cynthia is the Champion of the Sinnoh region. She appears in Caitlin's villa, and remains until she is battled, after which she will be present during spring and summer, and can be battled once per day in spring.
