The Fisher Price Ocean Wonders mobile is really the best thing I have bought ever. My son just loves it. I have been able to put him to bed awake and this wonderful mobile puts him right to sleep, or at least really entertains him until he drifts off. First, it has lights that project onto the ceiling in the patterns of fish, bubbles and swirls. Lullabies and soothing fishy sounds play as colorful fish float overhead. In the crib baby can play with the squishy pad fishbowl. Once baby is bigger, the mobile converts to sit on top of a dresser, so baby can still be entertained. I love the remote so you can keep the music going without baby seeing you sneak in to turn it back on. It hangs on the doorknob for convenience. I must say as much as I love this, there are a couple of things I dislike. For starters, the music doesnt play very long, I timed it and it is just over 5 minutes or so. Another thing, is when you need to change the batteries, you have to take the whole mobile off of the crib and take the back apart. Meaning you have to take off the piece that hooks onto the crib and then unscrew the battery compartment. That is a little time consuming.
