One favorite: the mermaid ice cream by Home Made Interest, above. Believe it or not, it’s a no-churn recipe, which means you can make it without an ice cream machine.

 

Mermaid party ideas: Octopus Dip by Dinner at the Zoo

Kids can’t live on treats alone, so I’m always looking for ways to dress up plates of healthy snack foods for kids party. Dinner at the Zoo made a crudite plate infinitely more adorable with this DIY bell pepper octopus and a scoop of homemade ranch dip. The recipe is on the site. Just be warned: those tentacles will likely disappear before anything else on the platter.

Mermaid party ideas: Sand Castle Cake by Living Well Spending Less

It makes sense that a mermaid’s cake might be made of sand, because, what is there to bake with, really, when you live under the sea? With that philosophical question in mind, I’m amazed by this mermaid party sand castle cake spotted at Living Well Spending Less. It looks delicious, and what kid wouldn’t thrill to the idea of eating “sand” for dessert?  Thankfully she offers step-by-step instructions because I definitely couldn’t figure this out on my own.

And yes, those starfish are edible. Make enough that all the guests don’t fight over them!

Ordinarily, I might look at these gorgeous sand dollar and seashell cookies and think: No possible way. But some of these sea-inspired cookies for mermaid parties by Sweet Sugarbelle are easier to DIY than they seem. I’d say start with the sand dollar cookies judging from her instructions.

 

Mermaid party ideas: Mermaid Mocktail by Our Family World

It’s important for mer-kids to stay hydrated, especially during the hot summer months, so have plenty of water and juice around. Keep a cooler filled with water bottles that you can wrap them with labels like these “Under the Sea Water” printables by Jen T by Design. Put out fresh fruit-infused water on the tables in sea blue or green pitchers. Or you can whip up some cool mermaid mocktails for the kids, such as the ones above by Our Family World. I love how something as simple as a fun, colorful straw can totally bring the theme to life.

Mermaid party ideas: Mermaid Superhero Printables by Mommy Scene

Katie from Mommy Scene made these free mermaid printables for her daughter’s mermaid-superhero party. (A brilliant hybrid party idea, don’t you think?) She used them for topping cupcakes and decorating tables, but I’d put them to use as a fun art activity for the kids.

Pre-cut the shapes from the site, arrange them on a table, and let kids mix and match to create their own mermaids that they can then glue down to a card and add their names. Don’t forget the sequins and sparkles! If you dare…

Mermaid party ideas: Sand Art Station by Pigskins & Pigtails

Pigskins & Pigtails set up a mermaid party sand art station party activity that looks like so much fun.Her instructions make it seem like a pretty straightforward activity to set up, and amen for that. That said, I’d be more inclined to do it outdoors (provided the day isn’t windy) or somewhere that I won’t end up vacuuming up the aftermath for the next 6 months.
