An Undersea Place to Call Home! (Japanese: 海底の城!クズモーとドラミドロ!! The Undersea Castle! Kuzumo and Dramidoro!!) is the 24th episode of the XY series, and the 823rd episode of the Pokémon anime. It first aired in Japan on November 20, 2014 and in the United States on February 7, 2015.

This episode was originally scheduled to air in Japan on April 24, 2014[1], but was postponed due to the sinking of the MV Sewol ferry in South Korea on April 16, 2014[2]; due to this, it was also subsequently skipped in the English-language broadcasts. It first made its world debut in South Korea on August 8, 2014, and then eventually aired in Japan on November 20, 2014[3], between XY050 and XY051. The English dub version, however, aired after When Light and Dark Collide!, during a four-hour marathon on February 7, 2015.

Our heroes take an excursion to the Muraille Coast before Ash's Cyllage City Gym battle. They spend some time fishing until Ash pulls up a Skrelp, which attacks Pikachu with its poison! Fortunately, they meet a couple along the beach road who heal Pikachu with a handy Antidote. Eddy and Lindsey are underwater archeologists in search of the Cussler, a luxury liner that sank many years ago. Our heroes decide to help them with their quest!

While Clemont and Bonnie stay above with Eddy, Ash and Serena join Lindsey in her submarine, and they dive toward the ocean floor. Sure enough, the wreck of the Cussler is there, and thanks to some crafty Dragalge who have fused it together with Acid, it's become a home for many different kinds of Water-type Pokémon!

A mysterious light lures them deeper into the wreckage, where they spot Team Rocket's submarine. The villains have come to claim the Cussler's sunken treasure, and their meddling has endangered the structure of the ship. With a little help from our heroes, the wild Pokémon manage to fix up their underwater refuge. But at the same time, Team Rocket escapes with the Cussler's safe—only to get caught in a whirlpool! Skrelp is caught too, but Froakie comes to the rescue, showing off its spectacular jumping skills…and giving Ash some ideas he would put to use in his upcoming Gym battle against Grant!

Who's That Pokémon?: Skrelp (US and international)

The title card segment focuses on Ash for this episode


  • During the fishing scene, Bonnie's hair on her hairpin is missing.
  • When Serena is watching Qwilfish on the submarine, Qwilfish's bellies are completely dark blue. This error was fixed in the Japanese DVD version and Pokémon Get TV.
  • In one scene, Lindsey's lower body is missing.
  • When the group of Luvdisc first appears and start playing with the group of Skrelp, Skrelp has Dragalge's voice.
  • When Ash grabs Froakie and Skrelp after rescuing if from the whirlpool, Boonie's hairpin is colored the same way as her bangs as she haves five of them instead of four for a few frames.

Dub edits

  • Unlike in other episodes, the narrator speaks entirely in a past tense in the dub, likely as a way to indicate this episode aired out of continuity.
  • As this episode was aired out of order in the US, it was aired out of order too in other international dubs that follow the US dub airing order.
