Kip. 67: Love at First Twirl!

67

A mysterious Pokémon has appeared and happily darts about in the sky above ... and it seems to have taken quite a fancy to Pikachu! Pikachu follows it out of the school, but it accidentally poisons Rowlet when Rowlet thinks that it's attacking Pikachu when they were only playing! While taking Rowlet to get help, they're spotted and chased by Team Rocket, but are rescued by Ash, Torracat and Lycanroc! Lusamine and the Aether Foundation determine that it's an Ultra Beast and name it Poipole. Lusamine asks Ash to take on the Pokémon as a partner—and our hero happily agrees. (Source: Wikipedia)
