As this is our first version of Bathly toy, we are taking a note of all customer feedback to improve the toy further. There is a switch on the bottom of the base designed to turn the wheels permanently on or off without the top sprinkler part. When the base is on the music plays continuously. As this brings a lot of joy and enhance the interaction with the child, it may be a nuisance to an adult hearing. As a temporary solution, we suggest placing a sticker over the speaker on the bottom of the base or even unplugging the speaker itself within the base. Please do open the base only at your own risk and handle all part with caution as you do not want to damage the moving mechanism inside.
