Press the music selection button of the toy to switch between different music.

There are two switches on the back of the hippocampus. The left switch adjusts the volume, the top of the right switch is short music, the middle is off, and the bottom is long music.

Its biggest function is to soothe children's emotions and help them fall asleep. Each piece of music plays for about 5 minutes, and is mixed with the sound of the waves of Grugu, which simulates the sound of amniotic fluid in the mother's womb, giving the baby a familiar feeling and a sense of security. The first few lines of each piece of music have a normal speed, and then get slower and slower, making it more conducive to sleep.
