Does anyone out there have a fisher price aquarium bouncer? I have just bought one on ebay and put it together and have found a loud squeeking rattling noise when the bubbles are released. This noise is so loud it blocks out the music/sounds being played and it is disturbing my baby even in the next room. I have emailed the seller on ebay and she is claiming it is not a fault that it has always been like that, thats how she says it is supposed to be. If anyone out there has one can you tell me if yours makes this noise. I just can't understand that if it is suppose to make this noise how your baby can relax and be soothed. Please help
