Product Description:
The baby will enjoy the classical-style music; soothing lights and water bubble show with this crib-attaching Ocean Wonders Aquarium. Five ocean friends swim peacefully across the aquarium screen while lights fade on and off in a tranquil pattern. Sweet songs or sound effects play, and bubbles rise to the surface. After ten minutes of play, both baby and you will feel councey and relaxed. There are three modes of operation so that as baby grows, the aquarium will continue to be entertaining. Busy activities help baby transition to quiet time. It requires 3 D batteries, which are not included. It Measures 13.38" x 4.5" x 11" and fits most standard cribs.

Rating : - Great product and great gift!
I should have written my review much sooner because we've been using this crib toy for about 20 months now and both the parents and baby love it!

Pay close attention to the "Product Description" of the Fisher Price Ocean Wonders Musical Aquarium Crib Attachment, which states: "It Measures 13.38" x 4.5" x 11" and fits most standard cribs."

None of the 4-in-1 sleep systems or convertible style cribs are what is considered a "standard crib" for this definition. [...]

This will not fit cribs that have a really wide top rail, or what I call the "sleigh-type" rail (see D. Lovely's customer image). The rail that is shown in the manufacturer's picture is narrow similar to what the "standard" or "traditional" cribs have.

For those who have had trouble installing it, what about trying to attach it at the head or foot of the crib instead? That is where we installed ours because it seemed more logical than the sides of the crib in order for the baby to look at it and play with it, even though ours would fit on either of the head/foot or side rails.

Also take note that there are screws for both attaching the battery box to the toy itself and screws for the battery box cover. It seems some people did not find all of the screws or did not have the instructions, etc.

I really like the fact that the battery box unscrews from the toy itself in order to replace the batteries; it's much more convenient than having to remove the entire thing from the crib to reach the battery compartment. With this newer model (produced in 2005 and discontinued in 2007) it plays 4 songs or 2 sound effects for 10 minutes and has 3 modes of play with lights, movement, bubbles, and music. It even has two little toys - a rolling crab and a starfish in a ball for babies to roll and play with. For $30 (original retail price), I think it does quite a bit and has worked wonderfully for us. My child can now even turn it on and change the modes and music without mommy or daddy's help.
