Kip. 24: Alolan Open House!

24

When the Pokémon School announces a special Visitors Day, Ash's mother Delia and Mimey come for a visit. Delia charms everyone, including all of Ash's Alolan Pokémon (especially Litten). Meanwhile, Ash is reluctantly trying to prepare a report he has to give in front of his classmates, the school visitors and his own mother. When the Team Skull grunts crash the festivities on Tauros and start causing mayhem, Ash, Delia and Ash's Pokémon team up to drive them off. (Source: Wikipedia)
