This is a Shimajiro lullaby toy from Benesse Kodomo Challenge Baby. Batteries are included, and it has been tested and confirmed to be working. You can use it right away. When you press the story button, Shimajiro says: "Good night~" "Cover up with your blanket~" "Pat pat~" "Let's sleep together~" and finally, it makes sleeping sounds. When you press the melody button, Shimajiro's dad's voice says: "Shimajiro, let's lie down and sleep." Then it starts singing, or a gentle music box sound plays. My child wasn't interested in it, so it was barely used. However, as this is a used item, please refrain from purchasing if you are concerned. #Shimajiro #SleepTraining - Character: Shimajiro - Material: Plastic - Brand: Benesse
