This is currently the only anime appearance of Phione.
This episode is the second episode when a genderless Pokémon falls in love with a main character's Pokémon. The first time was in Do Coil See Dreams of Electric Mice!? (1997).
The English dub title for this episode is a reference to the phrase "hold the phone."
This episode features one of the very rare times a Trainer's Pokémon battles an opponent without receiving any orders from their Trainer, but nevertheless still has their Trainer's consent.
