Game Ideas for a Mermaid Party
1. Mer-Monsters footsteps
Mermaids line up along one side of the room and at the other one child is designated Mer-monster. (The game is like Grandmother’s Footsteps). This Mer-monster faces the wall- not looking at the mermaids.
While the monster is turned away, the mermaids tiptoe- swim forwards and as soon as the Mer-monster turns around they have to freeze. If the mer monster watched anyone moving, they can be sent out or back to the start line. The child who manages to tap the shoulder of the mermonster wins

2. Mermaid life
In this game, the facilitator shouts out the actions below and children must follow the instructions for each action. The last ones to follow the actions are out and the game continues!
- To the magical kingdom – Run to one side of the room
- Swim ashore – Run to the other side of the room
- Deep dive- drop to the floor, lie on front and pretend to swim
- Magic pearl – open up hands to reveal a magic pearl with a ‘wow’ expression
- Up in the waves – pretend to wobble and splash into the water
This is a fun, high concentration and physical game- you can always take out one of two of these actions to simplify it for younger children, or reward the fastest child to avoid having to send people ‘out’.
3. Mermaid Mermaids Treasure
This game is similar to duck duck goose but with a theme. It’s a great one to play as children arrive (or as children might get tired of lunchtime at different rates) as new players can easily join and it’s fun and familiar to them. Children sit in a circle facing inwards. Child A walks around the outside of the circle and gently taps the group one by one on the head as they pass saying princess, princess, princess…..then, they choose one child (child B) to say dragon. child B jumps up and chases Child A around the circle. Child A has to run around the whole group and sit back in Child B’s space. If they manage, Child B becomes Child A in the next round. Otherwise, Child A has to play again until they succeed.
4. Mermaid statues
This game is like musical statues- children dance to music and when the music stops they have to freeze! Encourage them to do the craziest dancing they can manage- this is also a good strategy to get them burning as much energy as possible. You can either reward the most frozen statues or call out the funniest frozen positions.
Best Activity Ideas for a Mermaid Party
1. Mermaid Adventure Story
We have written a mermaid adventure story that you can read and even act out with the children at your party. This is a really fun activity- children will use their imaginations and feel like they’ve entered into a real magical mermaid land!
The story is about a mermaid called Coral whose superpowers are stolen by mer-monsters and hidden in a magical pearl in the depths of the sea! Coral and her mermaid friends go on an adventure to find it! The story is attached as a free PDF download below.
Suggestions: Coral’s mermaid friends must go on a quest to rescue her superpowers- and encouraging the children to actively go on the quest, and act out the challenges is a great way to bring this story to life.
In the next challenge, you can act wading through the super tangled sea weed “Oh my goodness this is so tricky- who is feeling tired?! Come on mermaids we can do it!”, you can get them to all shout “We can do it!” in chorus which is very cute!
For the swordfish challenge, have the children take out imaginary swords and wave them about- you can shout “Over there!” and have them all run to each imaginary swordfish in turn.
For the tiptoes challenge you could get one or two of the parents to play as the mer guards and the children have to sneak between them without being seen! Encourage the children to silently cheer for each other once each child makes it across- this is very cute too!
Make this section super engaging and get the children on board, and involved in pretending to be a part of the magic. If your child has a favourite mermaid story, you could tell that too.
Pro tip: for older children you can ‘take’ them to the magical story world by going on an imaginary roller coaster ride or sprinkling them with flying dust and flying there!

2. Mermaid Craft Activity
Make your own mermaid crown!
A craft activity is a really nice thing to do for a bit of downtime during a party. I often suggest it as children arrive. That way they can get involved straight away and having something to do can make integrating easier for children who are a bit shy at first. It’s also a lovely take-home gift.
We suggest making a mermaid princess crown! Here are some great instructions for a simple design to follow. Children can use coloured crayons to decorate, and maybe even some sticker jewels!
Music & Soundtrack Ideas for a Mermaid Party
The Disney movie has a brilliant soundtrack that I’m sure your kids already love! My favourite song by Far is Under the Sea so I would definitely use it for any of the dance moments! the new Disney movie would be great music too- here is the official Spotify playlist for it.
If you also want atmospheric music but not hit songs, you can try our favourite fairy music playlist here.
If you don’t have paid Spotify you can also look for playlists on youtube or just pay for a trial subscription of Spotify on their birthday party day.

Decoration Ideas for a Mermaid Party
Themed color balloons are a great deal of fun and make any space look festive- Create big bunches and tie them around any room. At the end of a party, you can give them to children to take home as a bit of fun and to reduce the waste at the end. We love this mermaid balloon assortment available on Amazon!
A large wall hanging around a central table (for instance where the speakers are or where you do the storytelling) can be really fun. One great option for this is disposable-themed tablecloths! It’s a cheap way to add color or themes and you can stick them up with blue tack or press pins because they tend to be light weight. For example: This mermaid-themed tablecloth on Amazon.
Food tables are also a great part of the decoration- if this is in the same room as the games, having it set up with a tablecloth and themed cups and plates adds to the atmosphere and it is also very functional. For example: This mermaid-themed table cloth on Amazon, or this great pink-themed one! And a themed tableware set such as this one!
It is inexpensive to get bespoke banners printed and this would make the decoration really special and personalized! You can even use it as a backdrop for taking photos of the guests with the birthday child as a special memento.
Music! It sounds weird but music really creates an atmosphere and adds to the feeling of the space. Movie scores can be great to have on in the background. We recommend The Holiday as a soundtrack for when the kids arrive.
Cute Food for a Mermaid Party
The best tip for food ideas is to keep it simple and keep it to food that children will love. To get the most out of the food experience, here are our ideas for adding some sparkle and creativity to the snack table!
Mermaid cake stands
This is a gorgeous mermaid cake stand that is perfect to display cupcakes or the tiny food cartons below! bear it in mind as you read through the rest of our food ideas!

‘Color’ themed platters
This is a really fun way to make a food table loop spectacular!
- Blue and Purple – blueberries, blackberries, dark red grapes, blackberry jam sandwiches, you can use natural food coloring to dye any dips like hummus or cream cheese, for crackers. It also looks really pretty to make light purple icing or purple melted white chocolate and drizzle over wafer biscuits or any white sugary deserts like white chocolate coated pretzels, marshmallows, and finger biscuits.
- For silver accents- drizzle melted white chocolate over any biscuits, wafers or fruits and cover in silver sprinkle balls or edible glitter- this will go down a treat!
- For rainbow accents- drizzle melted white chocolate over any biscuits, wafers or fruits and cover in silver sprinkle balls or edible glitter- this will go down a treat!
‘Imagination’ themed Jelly
A really fun thing to do for a party is make a huge bowl of jello and fill it with themed sweets inside! For a mermaid party, you could make a light blue jello and fill it with these dolphin jellies!.
You can also get little plastic figures online and put one of two inside the jelly – just be sure not to accidentally serve up on the day!
Creatively juice jugs
Make jugs of your child’s favourite juice but put on fun labels like ‘mermaid love potion’, ‘magical powers serum’ or ‘angle voice cocktail’ potion!
Cute individual veggie cups
Individual little holders for veggies and or fruit or popcorn are a really fun way to serve food. For a mermaid party, you could use gorgeous little blue and white cases, each with a couple of carrot/celery sticks, some grapes and some cucumber- check out this page on amazon for inspiration.
Popcorn lucky dip
Popcorn is a really fun party food that children love and can be easily customised to fit a theme. See this recipe here for pink popcorn- you can make this any colour by adding different colored food colourings and once you’ve poured the syrup onto the popcorn you can also sprinkle with multicoloured or silver and gold sprinkles.
You can also make a popcorn lucky dip (a total hit with all my nieces and nephews at parties) where you mix popcorn with themed party sweets. For example these dolphin jellies, or fish jellies.

Good Luck!
We’ve got you covered with budget-friendly options that will make your little one’s day a memory to cherish forever. So, grab your camera, snap lots of photos, and record those moments of mermaid magic!
