Whoever loves Ariel 


Did you admire Ariel as a child as she gracefully swam beneath the waves and collected treasures with her friends? Or perhaps your little one has already watched this wonderful film for the hundredth time?

Then it’s high time for an underwater party! Whether as a birthday celebration or a theme party: It’s an exciting theme that promises plenty of adventure.

You can plan the event as a relaxed evening gathering or organize a creative dance party with lots of mermen and mermaids. And a party for little guests is perfectly equipped with an exciting treasure hunt.

This decoration is perfect for an underwater theme

The most important element of successful underwater decoration is the color scheme. For background decorations in particular—tablecloths, garlands, and balloons—many shades of blue are suitable. They are often combined with white to evoke the foam caps on the waves. Pale shades of purple also fit wonderfully with the theme.

You can already see that many options are available to you. You can use this decoration:

  • Tablecloths
  • Garlands
  • Honeycomb balls and paper rosettes
  • Paper tableware
  • Napkins
  • Table confetti
  • Balloons
  • Hanging decorations

To make the underwater theme unmistakable, you’ll also need the right motifs. Seashells, mermaids, fish tails, crabs, starfish, and fish will make you feel as though you’re swimming underwater yourself. You can also scatter a little glitter.

Decorating for an underwater party

Whether it’s a children’s birthday party or a theme party for guests of all ages, an underwater party is a truly cool experience. With carefully selected decorations, you can turn the celebration into an unforgettable day.

For decorating large walls or a banner, a balloon garland is a great choice. It is subtle and works perfectly with paper garlands, honeycomb balls, and table decorations. As highlights, you can use foil balloons shaped like underwater creatures and jellyfish lanterns. Tip: Choose only a few so they don’t compete with one another for your guests’ attention.

You can easily decorate the table with paper tableware featuring a sea motif. It is lightweight, and if something falls, nothing will break. Also think about the food and drinks. With just a few details, you can wonderfully adapt them to the underwater theme. After all, we eat with our eyes too.
