Trivia

File:Title Card XY Ash.png

The title card segment focuses on Ash for this episode

• Professor Oak's Pokémon Holo Caster: Skrelp
  • Instead of Professor Oak's Pokémon Holo Caster, Professor Oak announced a new trailer for the new Pokémon 18th movie about Primal Groudon, Primal Kyogre and Mega Rayquaza.
• Serena and Grace narrate the preview for the next episode.
• This episode marks the first time when a Water-type starter Pokémon in Ash's team evolves.
  • This is also the first time since Round One - Begin!, 777 episodes ago, when a Water-type Pokémon has evolved under Ash's ownership.
• Frogadier remains outside of its Poké Ball for the entire episode.
• Team Rocket use a variation of their motto in the episode.

Errors

• When Clemont healed Sanpei's poisoned Greninja with a Pecha Berry, he said it was badly poisoned. Poison Jab inflicts regular poison to the target, not badly poison.
• In one scene, Greninja's mouth is colored blue instead of cream.
• In one scene, the pupil in Greninja's eyes are colored black instead of white.
• When Clemont and Serena were falling, Clemont was to the left while Serena was to the right. When Greninja saved Serena and Froakie saved Clemont, Clemont and Serena swapped places despite Greninja's tongue and Froakie's Frubbles not crossing each other's paths.
• When Saizō orders his Barbaracle to use Razor Shell on Team Rocket, the middle finger on Barbaracle's face is colored the same way as its face.
• When Barbaracle used Mud-Slap, it shot up two streams of mud off the ground, yet Pikachu, Greninja, and Froakie each got hit in the face by a different stream of mud, meaning a third stream appeared out of nowhere to hit Froakie.
