Mamas know that some afternoons are made for play that sparkles. And if your child is anything like mine—wildly imaginative, slightly obsessed with things in the ocean, and inexplicably drawn to anything shiny—then this Sparkling Mermaid Bait Sensory Tray is a total win.
We set this one up on a weekend afternoon when I was running on fumes and caffeine. I just needed something low-effort but high magic. And wow did this one deliver.
What started as a simple sensory tray turned into an all-out mermaid expedition complete with glitter storms, underwater treasure hunts, and the official crowning of a fish named Bubbles as the royal bait guardian.
Turns out, mermaid bait is serious business in toddler world. Who would of known?
Materials and Supplies

- Sectioned tray: the center becomes your mermaid bait mixing bowl, and the sections hold all the sparkly treasures
- Craft foam fish: cut from sheets in fun colors
- Assorted seashells: bonus points if they still smell like saltwater
- Iridescent chunky glitter: because mermaids don’t settle for matte
- Flat acrylic gems: the shinier, the better
- Plastic pearls and colorful beads: every bait mix needs pearls
- Small scoop and tongs: great for little hands and fine motor skills
- Bowl of water: for mixing and splashing (because…well…kids just love it)
How to Set It Up

Step 1: Cut Your Fish Shapes
Before you get started, cut simple fish from craft foam sheets. Nothing fancy—basic ovals with tails work great. We used purples, aquas, and pinks to stay in the mermaid color family.
Step 2: Arrange the Tray
We used a large round tray with sections (like a party platter), but a muffin tin works beautifully too. Here’s how we laid it out:
- One section for foam fish
- One for seashells
- One for glitter
- One for beads and pearls
- One for gems
- The center stayed empty for the all-important mermaid bait mixing bowl
Step 3: Add the Tools
Tongs and scoops are key. They’re fun, yes, but also sneak in a little fine motor practice. My son spent a good ten minutes trying to grab one tiny gem with the tongs—and when he finally did, he looked like he won the Super Bowl.
How the Play Unfolds

Now for the best part…watching it all come to life. Once you have it all set up, let your kiddo dive right in (pun intended). Here are some ideas on how we added play to our ocean-inspired sensory bin:
1. Make Mermaid Bait
This is where the fun begins. Kids mix beads, glitter, and pearls in the center bowl like they’re brewing an underwater potion. My little one proudly announced, “extra sparkly” for the mermaid queen’s pet dolphin. Who knew dolphins were part of the royal court?
2. Decorate the Fish
Once the bait is made, it’s time to decorate the fish. Gems become scales. Glitter becomes magic dust. Our fish ended up looking like they moonlight in Vegas.
3. Fine Motor Play
Don’t underestimate the value here—scooping, grabbing, and pinching builds dexterity. Plus, it keeps those little fingers busy long enough for you to sip coffee before it gets cold.
4. Imaginative Storytelling
This tray becomes a stage for storytelling. We had an entire saga involving lost treasure, bubble spells, and a glitter storm that only the bravest fish could swim through. These are the moments you remember—and the ones that help kids build creative confidence.
Frequently Asked Questions
Can I skip the glitter?
Absolutely. If you’re glitter-averse (understandable!), try sequins or just stick with shiny beads and gems. The sparkle will still shine through.
Is this okay for toddlers?
With supervision, yes. If your child is still mouthing objects, skip the small pieces or go larger with jumbo buttons and foam shapes.
What age is this best for?
We’d say 3 to 6 is the sweet spot, but younger kids will enjoy it with guidance and older ones might surprise you with how elaborate their stories get.
How do you clean it up?
Use a plastic tray or shallow bin to catch most of the mess. A handheld vacuum or lint roller works great for runaway glitter or beads.
Can this be a group activity?
Definitely! Set up multiple trays or let kids take turns mixing their own bait recipe.
