Under the Sea Party Supplies

Make a splash with our under the sea party supplies — an ocean of decorations, tableware and party bag fillers perfect for mermaid parties, pirate adventures and seaside celebrations. Whether your little one loves fish, dolphins or sea creatures, our underwater collection brings the ocean to life.

Under the Sea Decorations & Balloons

Create an underwater wonderland with ocean-blue balloon arches, fish and starfish foil balloons and sea creature hanging decorations. Shell garlands, coral reef backdrops and wave-print bunting in aqua, teal and coral add depth to your underwater scene. Giant inflatable sea creature centrepieces add a playful wow factor.

Ocean Tableware & Accessories

Serve food from the deep with sea creature plates, ocean-print cups and fish-print napkins in shades of blue, teal and sandy coral. Shell-shaped cake toppers and mermaid tail candles make brilliant finishing touches to your ocean-themed birthday cake. Coordinate with a blue tablecloth scattered with shell and starfish confetti for the full effect.

Under the Sea Party Bags & Fillers

Send young explorers home with ocean-themed treasures — sea creature toys, shell craft kits and nature activity booklets all make excellent party bag fillers. Many of our underwater fillers are plastic-free, making them a great eco choice for ocean-loving families.
