Decorate your mantel with seashells and sand buckets, or choose a different color to coordinate with the color scheme you’re using.

Gingham themed table runners.
Get a pretty seashell tablecloth that you can use for the party and afterward. This would be a pretty design to perk up your home after the party is over, and during hte party it will create a nice under the ocean feel.

Get some kids’ sand pails and shovels to use as decorations, or if you have the party outside, use real sand as a base to put them on for decorations.
Sea themed baby shower food ideas.
Food for an Under the Sea themed baby shower could lean heavily on seafood, but be careful not to go overboard (pun intended.) Depending on whether your party is going to be formal or more casual, you could theme it like a beach picnic, a beach bonfire cookout, or set up a more formal buffet with seafood choices that your guests will love. If you want to go all-out, you can even hire a caterer to set up an ice bar with fresh oysters.
Before you choose the types of fish, read this article from the Mayo Clinic about which seafood pregnant women should avoid. The mother-to-be should be able to enjoy the food at her own shower! Definitely avoid raw seafood, and some of the types of fish that are recommended to not eat if you’re expecting.
Pearl cake pops or balls.
Make cake pops (or buy them) and dust them with a reflective edible luster dust to give them a pearl sheen. You can get white Monegasque pearl dust on Amazon, and this video will show you how to use it on cakes and cupcakes:

Baby shower fruit platter.
Serve a fruit platter or set up a buffet with tropical fruit and selections like pineapple and oranges. Fruit is a good choice for everyone, and it’s a break from the cupcakes and other sweets that are the focus of most baby showers. Go with summery, beachy flavors like coconut, pineapple, citrus, and add some summery lemon sorbet to go with it.
Themed cake or cupcakes.
An under the sea themed cake or cupcakes is a fun addition to an Ocean party. You can get edible ocean decorations for an Under The Sea cake on Etsy, like this set that’s personalized. It’s technically for a birthday, but it could be used for a baby shower with the mother–to-be’s name on it!

A fresh juice bar.
Have a drink station set up where you have pitchers of fruit juices and flavored water. If you want to make them themed to put a spin on them, you can call them things like “kelp juice,” “pirate’s grog,” and “ocean water.”

Under The Sea party games and activities.
Fishing pond.
Set up a “fishing pond” with little fishing rods that have magnets on the end, then get fish that have a magnet on them in a big bucket to grab. (Don’t let guest peek into the bucket when they go fishing.) Give each guest one try to win a prize (or two if you’re feeling generous) and write the name of the prize on each fish. the prizes should be good doorprize-quality, and when people see that they have a chance to win something they really like, they’ll definitely want to participate.
You could also do this as people leave so that they’re fishing for their party favors!
Seashell hunt.
If you have an outdoor space, hide a bunch of shells around the yard and give people a list of the ones that they need to find in the shortest amount of time. The first person to find everything on their list wins a prize.
