Invitations set the tone for any event, and an under the sea themed baby shower is no exception. Create invitations that feature an underwater scene with cute sea creatures like octopuses, seahorses, and starfish. Use shades of blue and green to evoke the feeling of being under the sea.

Use a die-cut mermaid tail shape as the base for your invitations. Add details like glitter, pearls, and shells to make them extra special.

For a unique and creative invitation, send your guests a message in a bottle. Fill a small glass bottle with sand and a rolled-up scroll of the party details.

Use a seashell-shaped die-cut or a printable template to create invitations that are shaped like seashells. Add a cute message like "Come dive into our under the sea baby shower!"

Create an underwater world with decorations that transport your guests to the depths of the ocean. Start by covering the party space with blue and green streamers, balloons, and tablecloths. Hang fishnets from the ceiling and attach plastic sea creatures like starfish, seahorses, and crabs to them. Place small seashells in glass bowls or vases, and add tealight candles to create beautiful and elegant centerpieces. You can also scatter seashells around the table for an added touch.

Create jellyfish lanterns by attaching long strips of crepe paper to the bottom of paper lanterns in different sizes and colors. Hang them from the ceiling to add a fun touch to your decor.

Balloon garlands are also an easy way to create a fun and whimsical atmosphere. Use blue and green balloons to create a wave-like effect, and add metallic silver or gold balloons to resemble bubbles.

Seafood-inspired dishes are a must-have at your under the sea baby shower. Serve up delicious seafood appetizers like shrimp cocktail, crab cakes, and fish tacos. For dessert, create blue velvet cake pops shaped like octopuses, candy pearls, or jellyfish cupcakes with flowing tentacles made out of fondant. You can also make cupcakes with blue frosting and top them with gummy fish or use a mermaid tail cake topper. 

Create a punch bowl filled with blue Hawaiian punch and add some fish-shaped ice cubes for a fun touch. Serve up refreshing mocktails with ocean-inspired names like "Mermaid Margarita" or "Seabreeze Spritzer." Provide colorful paper straws to add a festive touch.

Games and activities

Games are always a hit at baby showers, and an under the sea theme provides plenty of opportunities for fun and creative activities. Play games like "Guess the Baby's Due Date," "What's in Your Purse? Under the Sea Edition," or "Name That Sea Creature." 

Set up a photo booth area with props like mermaid tails and snorkel masks so guests can take silly underwater-themed pictures.

What about a mermaid hair and makeup station where guests can get a mermaid makeover? Provide temporary hair color sprays, glittery makeup, and mermaid crowns for guests to wear during the party.

You can also set up a crafting station where guests can create their own ocean-themed crafts like seashell picture frames, painted sea glass votives, or sea creature plush toys.


Party favors are a great way to thank your guests for joining in the celebration. Send them home with fun under the sea themed party favors like custom-made cookies shaped like seashells, starfish, or other sea creatures. Wrap them in cellophane bags and tie with a ribbon in shades of blue or green.

You can also make bath bombs: Fill small clear bags with under the sea-themed bath bombs or fizzies that look like seashells or bubbles. You can also add a personalized tag with a message like "Thanks for making a splash at our baby shower!"

Make your own sea salt scrubs with ingredients like coconut oil, sea salt, and essential oils. Place them in small jars or containers with a cute label and ribbon.

Make sure your guests feel appreciated and remind them of the special time they had celebrating the arrival of the little one by having custom-made keychains shaped like sea creatures or with under the sea-themed designs. You can also add the name of the mom-to-be and the date of the baby shower for a personalized touch.

An under the sea themed baby shower is not only fun and playful, but it also provides endless opportunities for creative and unique decorations, favors, and activities. The blue and green color scheme can be used throughout the party space to create a serene and calm atmosphere, and the sea-themed decor will transport your guests to an underwater world filled with wonder and imagination.
