15+ Mermaid Party Games & Activities
Welcome to Sugar, Spice & Glitter! Please note, this post may contain affiliate links. For more details, see our Full Disclosure.
Even if you’re lucky enough to host your mermaid birthday party in the summer, it’s still a good idea to have a couple water-free mermaid games & activities for your land-loving guests, or those just seeking a break from pool time. Most of these ideas are also great if you’re having an indoor mermaid party, or even a mermaid play date!
My daughter has a summer birthday so we’ve always lucked out with outdoor parties – lots of room for running around and the option to set up pools or water-based activities.
However, I’ve learned that you should always have a a few activities planned – whether you get rained out of the perfect outdoor party or one of the activities doesn’t pan out. We’ve had princesses be late or kids who prefer quieter activities to group ones (etc) and being prepared for those eventualities will make your party smoother and stress-free.
My personal recommendation is to plan one activity per half hour of the party, up to a maximum of 8 activities – this will be one or two more than you need, but some activities might not be a hit with the kids, or something might not work out and this way you’ll be prepared. (You can always leave the supplies for those bonus activities/crafts close by but in their packaging and then return them after the party if they don’t get used.)
Some of your mermaid party activities might be games, but some might be quiet craft corner projects or sensory activities that kids can do independently when they need a bit of a break from the party hubbub. (Group crafts are also great for helping quiet kids connect with the more outgoing kids – and keep the kids all in one place temporarily.) Keep in mind that if you plan to open gifts at the party or are serving a meal (not just cake and treats), that those can count as an activity.
We also have a Printable Mermaid Activity Pack and Printable Mermaid Board Game that would be great for quiet activities or loot bag additions.
Alright, now that I have that out of the way – let the mermaid games begin!
Active Mermaid Games
This Captain Hook Ring Toss from Miss Meg Story Time is such a fun DIY take on the classic ring toss game, or try out this easier DIY version by East Coast Mommy.
While it worked for her Pirate Party, I think this Treasure Dig from Be Fickle could easily be a Mermaid Treasure Dig – or you could do this foam version I shared on the Letters of Literacy blog.
For an easy DIY Mermaid Game, check out this seaweed limbo game from 365 Days of Crafts, or that cute seaweed relay game (which I can’t find a source for).
All of the work is done for you with this Pin the Tail on the Mermaid Printable from Etsy.
A Mom’s Year had some amazing ideas for her mermaid party, but this Mermaid Race totally takes the cake!
A quick and easy DIY Fishing Game is a great indoor or outdoor game, and if you don’t have time to make one check out this Laundry Hamper Fishing Game from Munchkins and Moms that would take less than 5 minutes to set up. (You can also buy a pre-made one if you’re on the ball – I like this felt version from Etsy.)
Oh, and I almost forgot: Pass the Mermaid from Bachmanville is such a great activity for younger or mixed age groups.
Mermaid Crafts & Activities
I’ll put together another collection of our favorite mermaid crafts because not all can be made and completed in the time allowed at a birthday party, like our mermaid tiara craft. In the meantime I have this fun collection of 60+ Finding Dory Crafts, Activities & Foods – many of which would fit a mermaid theme.
Light-up Mason Jar Aquarium Craft from Tip Toe Fairy is a cute and quick craft that can be made at a mermaid birthday party.

Our Mermaid Tiara can be made lots of different ways – you can make them at the party, or hand out as favors afterwards.
I LOVE this Mermaid Lagoon from Small Potatoes – it would be such a great calming activity for kids who need a break from other activities.
This Mermaid Play Dough Invitation was such a hit at our mermaid party and on a rainy day in our daycare. (I doubled the batch for the party so we could package up some of the play dough and materials for mini Mermaid Play Dough kids for party favours.)

This Sparkly Mermaid Slime is easy to make and clean up with a bit of vinegar.
These Mermaid Necklaces from Mama, Papa, Bubba would be quick and easy for a mermaid birthday party.

Set up a table with some mason jars and the simple ingredients for this mermaid sugar scrub for an awesome party craft kids can bring home (you can even pre-mix the colors and scents so the kids are just focusing on layering the sugars – a fun twist on sand art!)
Mermaid Peg Doll Craft from Oriental Trading (love when you can just buy everything you need for a craft in one click)

Kids can put on their own mermaid productions, or just personalize their own mermaid puppets with this simple mermaid shoebox craft. (Just do any of the box cutting before the kids arrive.)
We have a great textured sand slime recipe that would be great for playing with at the party – or sending home as a party favor.

Another fun one for the gift bags is our mermaid tail soaps – we’ve found so many uses for that silicone mermaid tail mold!
Ella and I recently made Mermaid Flower Pots which would make a great craft for older party guests.

Our Mermaid Pearl Floam Slime is less messy than our original Mermaid Slime and could either be a fun party activity or loot bag item.
And finally, our Mermaid Sun Catchers are another fun quiet activity you can set up for party guests who need a few minutes break time from the party excitement.

While we made our Mermaid Wands in advance of the party, it would be cute to stick out the dowels, starfish, and some gems and ribbon for kids to personalize their own as a DIY party favor.

Thank you very much for the information. I lost my job and have to rely on social security now. Because I’ve just turned fifty years old, people are not likely to hire me. Officially, they never tell me that it is because of my age. But I know better why they are all rejecting me. The same happens with young girls I tried to ask out. They never told me that I was old. They just never confirmed a meeting. So I found sex meet website and will try my luck there this weekend. Have a great life. I hope other commentators will never go through the situation I went through.
