Decorations

When it comes to an Under the Sea-themed party, decorations are key to creating that magical underwater atmosphere.

Have you ever walked into a room and immediately felt transported to a different world just by the decorations?

That’s the magic you can create with the right party supplies!

The goal is to bring the ocean to life, and with a few thoughtful touches, you can transform any space into an undersea wonderland.

Tableware

To set the tone, start with your tableware.

What better way to immerse your guests in the theme than by using plates, cups, and napkins that feature ocean patterns or sea creatures?

Look for vibrant colors like coral and turquoise, which instantly remind everyone of the sea.

We offer beautifully designed paper goods that can really elevate your table setting.

Our curated collection blends contemporary designs with traditional charm, making it easy to create a cohesive look. Whether you're setting the table for a casual gathering or a formal celebration, our products fit seamlessly into any party style and help create a stunning tablescape.

Banners and Backdrops

To really bring the magic of the ocean to life, consider adding banners and backdrops.

Can you picture a banner that spells out fun phrases or the event's name, with the background of an ocean scene filled with coral reefs, fish, or even mermaids?

It’s these small details that turn a room into an immersive undersea adventure.

Using high-quality designs from My Mind’s Eye ensures a striking visual impact. We offer customized options that give a unique twist to traditional themes, making your event stand out. 

These decorations provide the perfect backdrop for themed photo opportunities, ensuring your guests have something fun and memorable to take home.

Balloon Arrangements

Balloon arrangements can add a whimsical touch to your decor.

Opt for balloons in various shades of blue, coupled with metallic and transparent ones to mimic bubbles. Consider including balloon shapes like fish or seahorses to enhance the theme.

We offer stylish balloon arrangements that harmonize effortlessly with the rest of your decorations. Our distinct design approach adds a creative flair that suits the playful under the sea atmosphere, ensuring everything ties together beautifully.

Centrepieces

Centerpieces are a focal point at any party, and for an Under the Sea theme, they’re your chance to get creative.

Consider glass bowls filled with sand and seashells, or small decorative aquariums with toy fish. For a little extra magic, add LED lights in shades of blue to simulate water reflections.

We offer distinctive centerpieces that perfectly match a variety of themes. Our creative designs not only fit beautifully with your party decor but also add a touch of elegance, showcasing a mix of modern style with well-loved traditional elements.

Lighting

Proper lighting can transform any space, creating a magical underwater effect.

Use blue and green lights to simulate water or hang string lights to mimic the sparkle of the ocean's surface. LED lights can be strategically placed for added ambiance.

Using our supplies ensures that your lighting complements the rest of your event's decor.

With our innovative designs, you can achieve an enchanting atmosphere, reflecting both a modern and timeless aesthetic that enhances the entire party experience.

Costumes

When it comes to an Under the Sea themed party, costumes are a fantastic way to enhance the experience and take the fun to the next level.

Have you ever noticed how a themed costume can instantly transport you into the spirit of the event?

Whether you're hosting the party or attending as a guest, wearing the right costume helps bring the underwater theme to life in the most magical way.

Let’s dive into some creative ideas for both adults and kids!

Adult Costumes

Adults can explore a wide array of costume options to join the Under the Sea fun.

Classic choices include mermaids or sea captains. These costumes often feature flowing materials with shimmering finishes to imitate ocean waves. Other popular themes include pirates and sailors, which can add a rugged twist to the party.

For a more whimsical look, consider dressing as a sea creature like a jellyfish or starfish. Look for costumes with luminous effects or oversized fins.

Most importantly, ensure comfort by choosing lightweight and breathable fabrics. This will help you enjoy the party while keeping cool.

Kids' Costumes

Children have endless possibilities when it comes to Under the Sea costumes.

Popular choices include colorful fish or playful characters like Ariel from The Little Mermaid. Costumes can feature bright colors, glitter, or shiny scales to captivate young imaginations.

For a cute option, choose an octopus costume with long fabric tentacles for little ones. Costumes that offer flexibility and easy wearability will let kids move around freely.

Comfortable fabrics are essential, especially for toddlers, to keep them content all day. It’s all about balancing fun designs with practicality for the youngest party attendees.

Accessories

Accessories can take any Under the Sea costume to the next level and add the finishing touch that makes the costume even more magical.

Imagine a headband with seahorses or shells or a sparkling fish-themed makeup look—these little details bring the costumes to life.

For an added touch, you can include ocean-inspired jewelry, like starfish necklaces or sea-themed earrings. And for a bit of fun, why not add body glitter or temporary tattoos to mimic sea spray?

My Mind’s Eye offers a wide selection of party accessories that can perfectly complement any costume, ensuring your guests look and feel their best.

Food and Beverage Ideas

When you’re planning an Under the Sea themed party, the food and beverages are just as important as the decorations and costumes.

Who doesn’t love a party with creative food that ties into the theme?

Think about the excitement on your guests’ faces when they see snacks and drinks that fit the ocean vibe!

It’s all about creating that immersive experience, and your party menu can really help you do that.

Sea-Themed Snacks

Make a splash with snacks that capture the essence of the sea. You can try crab-shaped sandwiches, using bread and fillings of your choice.

Seashell macarons with teal and blue frosting can add a sweet touch.

Seaweed scrolls, made from wrapping nori sheets around rice and vegetables, provide a savory option. These themed snacks don't just taste good; they fit the party theme perfectly, making them a big hit with guests.

Beverage Suggestions

Beverages should also contribute to your ocean theme.

Mermaid punch, a mix of blue fruit punch and soda, looks appealing and refreshing.

Ocean blue lemonade popsicles are another fun idea, especially for summer parties.

Don't forget simple drinks like water with sliced lemon and mint, which stay on theme with a touch of elegance. Beverages aren't just about quenching thirst—they enhance the visual and thematic experience.

Cake and Dessert Inspirations

Desserts provide a perfect opportunity to impress.

Consider a cake decorated as an underwater scene, complete with fondant sea creatures. Cupcake toppers shaped like starfish or sea turtles make for charming accents. Whale-shaped cookies or mermaid-tail cupcakes are delightful treats as well.

All these elements create an immersive theme experience for your guests, rounding out your menu with style and creativity.

Party Activities

What’s a party without fun activities to keep the guests entertained?

For an Under the Sea-themed celebration, the right activities can make your party even more memorable.

Have you ever been to a party where the activities perfectly fit the theme and made you feel even more immersed in the fun?

That’s what we’re going for here!

From creative crafts to engaging games, these activities will ensure your guests are just as excited about the experience as they are about the decorations and food.

Games

Games should be fun and fit the theme.

You might start with a treasure hunt.

Hide small treasures like toy fish or sea shells around the party area. Give kids clues to find these hidden treasures for added excitement.

Another great game is "Pin the Tail on the Mermaid."

A twist on a classic, this game is sure to make young guests giggle.

For older kids or adults, organize a "Fishing Game" using a magnet and toy fish with metal rings, providing an engaging challenge for all.

Craft Stations

Set up craft stations where kids can unleash their creativity.

Consider making ocean-themed bookmarks.

Provide materials like ribbons, markers, and stickers of sea animals. This activity encourages kids to create keepsakes that remind them of the day.

Another craft idea is creating sea creature hats.

Use paper plates and markers to design hats resembling jellyfish or fish. It’s easy, and fun, and lets kids wear their sea-inspired art throughout the party, doubling as a fun photo opportunity.

Entertainment Options

Bringing in themed entertainment can elevate the party.

Hire a performer to dress as a mermaid. They can engage with children, sharing stories of undersea adventures. It’s a magical way to captivate young imaginations.

Alternatively, show a sea-themed movie.

Set up a cozy viewing area with bean bags and blankets, where kids can enjoy films like "Finding Nemo" or "The Little Mermaid." These options ensure kids will be entertained and the theme remains consistent.

Favors and Gifts

Choosing the right favors and gifts for your guests can be a great way to show appreciation and add a memorable touch to your Under the Sea-themed party.

Ever been to a party where the favors were so thoughtful and on-theme that they instantly became a keepsake?

That’s the magic of the right party gifts—they don’t just thank your guests, they leave them with a piece of the celebration to take home.

Guest Goodie Bags

Creating the perfect goodie bag can make your under-the-sea-themed party memorable for guests.

Consider including items like ocean-themed stickers, mini sea creature toys, and fun candies with a sea twist. These can be presented in colorful, ocean-themed bags that align with your decorations.

Emphasizing variety while sticking to the theme is KEY.

Think about combining small, budget-friendly items that collectively offer a delightful experience. 

My Mind's Eye offers a great selection of stylish party supplies, including bags and tags, for crafting memorable goodie bags. Our assortment includes both contemporary and traditional designs, all made in the USA.

Thank-you Notes

Sending thank-you notes is a thoughtful way to extend gratitude to your guests after the celebration.

Opt for stationery that complements the ocean theme, perhaps featuring seashell or starfish designs. Personalize each note by mentioning something specific to the guest’s presence or gift, making them feel cherished and appreciated.
