b. Colorful Mermaid Tail
Mermaid tail invitations are fun too! Especially this colorful mermaid birthday invitation with gorgeous font.
2. Beautiful Mermaid Decorations
Though invitations set the initial excitement for the party, the decorations give your party the feeling of being “Under the Sea.”
I know it can get to be expensive to do it all.
To keep it simple, pick a focal point or two, for example, an enchanting entrance and captivating dessert table.
2.1. Enter the World Under the Sea
Create an enchanting entrance with lanterns, pom poms, and balloons. Mix in a few jellyfish lanterns for extra excitement.
Hang the lanterns and pom poms low enough for the kids to really feel like they are “swimming” into a magical world of mermaids.
What colors should you use? Aqua, turquoise, and blue are always a good choice. But you could also combine those colors with pink, purple, gold, and transparent balloons.
The little guests will have fun going through the colorful entrance to reach the mermaid party in the magical world under the sea.
2.2. Easy DIY Mermaid Backdrop
With sheers, tulle, and ribbon you can create a beautiful inexpensive backdrop for your mermaid dessert table.
Put strings of Christmas or fairy lights behind the sheers for added sparkle. Adorn the whole thing with seashells and pearls.
Grab the backdrop materials:
- This shimmering blue/purple tulle roll would be perfect!
- Blue fairy lights or white fairy lights make the tulle sparkle
- backdrop stand (I have this one and it’s great.)
2.3. Beautiful Under the Sea Backdrop
Why have only one backdrop when you can have two. Place this 7×5 ft beautiful Under the Sea World backdrop somewhere in the party area and use it as a photo backdrop.
You could hang sheers, satin, or tulle on both sides to frame this beauty.
2.4. Treasure Chest
A real attention grabber: a treasure chest lined with tulle and filled with
- chocolate coins
Place a the trunk on a table and you’ll have mermaids gathered around it in no time.
Use it to display game prizes or party favors!
2.5. Cute Mermaid Quotes
Once you have picked your focal points you can add the small details that make the party even more amazing.
Frame cute mermaid images and quotes to delight your birthday girl and her friends.
You can find fun mermaid printables at Artsy Momma or you could come up with your own quotes. Maybe your daughter has a few sweet mermaid quotes too.
2.6. Mermaid Eggs
What a cute idea! Mermaid eggs! This easy Mermaid DIY project is from Adventure In A Box.
Find out how how to make these pretty mermaid eggs. Use them as party decorations or favors. These would be perfect also for a Mermaid Baby Shower!
2.7. Mermaid Dream Catcher DIY
Dream catchers are pretty popular. Make a few to display at the party or put together mini size dream catchers to be used as party favors. You’ll find the Mermaid Dream Catcher instructions at Red Ted Art.
This would be a fun mermaid party activity!
2.8. Twirls and Polka Dots
You can easily create a magical feel to your mermaid party by hanging polka dot garlands from the ceiling. Or use them as a backdrop behind the gift table.
These garlands are easy and inexpensive to make yourself.
2.9. Fish and Sea Weed
And don’t stop with polka dots. Hang up streamers or attach fish cutouts to curling ribbon and it will look like you are surrounded by a school of fish.
The little mermaids at your party will love to hang out with the fish.

2.10. Mermaid World
Sweet Mermaid World printable from Hattifant. Print and color. Simple Fun.
Maybe your daughter would like to color hers before the party and display it as a decoration. Or this could also be a party activity and the girls could each color their own set.
2.11. Pearls, Tiaras and All the Twinkling Jewels
I keep mentioning tulle but it really can add some nice texture to your party. Use tulle and sateen as table runners with pearls, tiaras and other jewels as centerpieces.
Sprinkle seashells on the tables.

I have several yummy treats for you to choose from. Or if you are like me you will have a table full of sweet treats.

4.6. Musical Seashells
Draw giant size seashells and cut them out. Tape them to the chairs. Set up the chairs in a circle and turn on the music. Play just like you would musical chairs.
4.7. Freeze Swim
Play just like you would freeze dance. Dance and “swim” around while the music is playing. When the music stops: freeze.
4.8. Crab Walk Relay
Make a relay course by using pool noodles. Anchor a pool noodle arch to the ground and hang strips of streamer from it for sea weed.
You could set up a few arches in a row for each team to crawl under.
4.9. Obstacle Course
Crab walk could be also part of an obstacle course. Along with a bean bag toss. Popping balloons. Finding a treasure in a shipwreck.
4.10. Story Time
Not exactly a game. But could be a nice quiet activity or turn it into an action-filled activity and choose a girl or two to act out the story.
Plenty of mermaid stories to choose from. Throw a few starfish or seashell-shaped pillows on the floor for cute seating; and go on magical journeys with mermaids.
