well, I did have some ideas

Meloetta - its normal type means it naturally has a large heart, and with its forms the heart will either grow bigger with psychic or grow stronger with fighting.

What's also interesting is that Meloetta's heart will follow any rhythm it hears. It'll mimic any other heartbeat, or will follow the rhythm of any music it listens to. The organ beats to the bass, and will pound as hard as the music is loud. Extensive testing showed that a Meloetta's heart does not grow strained, and it rather likes when its heart thrashes from the loud music. Even when the music had long pauses, its stopped heart didn't seem to deter it. It was as if the music playing in general kept its blood flowing and nothing could overload its heart.
