Shell-abrate in style: How to plan the perfect Mermaid Under the Sea Party
If you’re planning a birthday party for a little ocean lover, a mermaid-themed celebration is always a magical choice. Think shimmering seashells, pastel ocean colours, glittering treasures and plenty of under-the-sea imagination.
With a few little touches, you can transform your space into a dreamy underwater world that will delight kids and grown-ups alike.
Inspired by the colourful, playful style you’ll find on Pickle & Podge, this guide will walk you through how to plan the perfect mermaid party, from decorations and activities to food and dress up ideas.
Let’s dive in!
Set the scene
Start with a colour palette of soft sea blues, aqua, lilac and shimmering hints of coral and pearl.
Hang our mermaid themed Pickle & Podge Garland across a wall, shelf or party table to create the perfect under-the-sea backdrop. Filled with playful mermaids and ocean details, it instantly sets the tone for a magical celebration.
Add extra ocean sparkle with:
- Paper streamers in flowing blues and greens to mimic waves
- Shiny foil curtains or iridescent fabric for a watery shimmer
- Paper shells, starfish or bubbles cut from card and hung around the room
- Scatter a few seashells or shiny “treasures” on the table for the finishing touch
Feed those hungry mermaids
Kids’ party food doesn’t have to be complicated, just a little creative…
- Serve crab sandwiches, using mini croissants and adding eyes on cocktail sticks
- Shell pasta salad is an easy and perfectly themed savoury option
- Turn fruit skewers into “magic wands of the sea” using melon, grapes and berries
- “Star fish” rice crispy snacks, or “Oyster shell” macarons make the perfect sweet treats
- Add a bowl of blue jelly with gummy fish swimming inside for a fun ocean touch
- Edible glitter will add an underwater shimmer to anything!
Simple food with a splash of imagination always feels extra special.
A cake showstopper
Turn an easy and simple cake into the perfect table centrepiece with our Pickle & Podge Mermaid Cake Toppers. Just pop them on top and suddenly your cake becomes a magical under-the-sea scene, with mermaids ready to celebrate and plenty of ocean charm.
Outfit magic
The birthday child should feel like the star of the ocean! Our Sirena Capelet and Tutu Skirt are the perfect combination for a magical mermaid, with hand-embellished iridescent sequins in a scale design, this ocean inspired set is the underwater treasure you have been looking for.
Time for fun!
Plan a few simple activities to keep little mermaids entertained:
- Decorate seashells with paint pens or glitter glue
- Make mermaid crowns, shell necklaces or wands – these make the perfect take-home keepsake too!
- Egg-box treasure chests or toilet roll mermaids are an easy crafty party activity
- Under-the-sea treasure hunt with shiny coins, shells or small toys hidden around the room or garden
- Have an underwater dance party – swim like mermaids, glide like sea turtles and twirl like jellyfish. Or for a calm-down classic? Sleeping Sea Creatures – just like Sleeping Lions, but with fish and mermaids drifting peacefully in the ocean.
The best mermaid parties feel magical, colourful and full of imagination. Focus on playful decorations, simple food with fun twists, and activities that let kids dive into a world of ocean adventure.
With mermaid garlands, charming cake toppers and a few sea-inspired treats, you’ll have everything you need to throw a fin-tastic mermaid birthday party that kids will remember long after the last bubble has been popped!
