What You’ll Need To Make Ocean Jello Cups

• Blue Jello (berry or tropical punch flavors work best)
• Gummy octopus or other sea creature gummies
• Gummy fish or sharks
• Mini paper drink umbrellas
• Nerds candy (to represent colorful “rocks” or ocean gravel)
• Clear plastic cups or bowls

You can also find most of these ingredients at any grocery or dollar store, making this an easy last-minute idea that still feels special.

How to Make Ocean Jello Cups

1. Prepare the Jello according to the directions on the box. Let it cool slightly so it’s safe for kids to help.
   

2. Pour a layer of Nerds into the bottom of each clear cup to resemble pebbles or coral on the ocean floor.

3. Carefully scoop or pour the Jello into the cup over the Nerds. Fill it about three-quarters of the way.

4. Add gummy fish and octopus near the top before the Jello sets completely. For extra fun, gently press some candy partway into the Jello so it looks like they’re floating.

5. Once the Jello has fully set in the fridge, top each cup with a mini umbrella to complete the tropical look.

Kids will love seeing the layers and pretending their ocean animals are swimming through a sugary sea.

Why This Snack Activity Is a Great Learning Tool

This treat might look like a dessert, but it’s also packed with developmental and learning opportunities.

• Fine motor skills are strengthened as children pour, scoop, and place each element carefully
• Sequencing and direction-following are practiced by preparing ingredients step by step
• Scientific observation happens naturally as kids watch Jello change from liquid to solid
• Sensory engagement comes through texture, color, smell, and taste
• Imaginative play is sparked by building ocean scenes and storytelling with their candy creations

You can also reinforce language development by encouraging children to describe their creations and narrate what’s happening under the sea.

Ideas to Extend the Activity

Looking for ways to turn this simple snack into a full thematic experience? Try these fun and educational extensions

• Set up a “build-your-own ocean cup” bar where kids choose their sea creatures and toppings
• Pair the snack with an ocean scavenger hunt or trivia game about marine life
• Have kids draw or paint their ocean cups before making them, then compare their artwork to the real thing
• Turn it into a science lesson—discuss how gelatin sets, and compare ocean habitats from books or videos
• Use paper and crayons to label parts of the cup like “ocean floor,” “sea creatures,” and “waves” for a vocabulary boost

This activity is also great to use during summer school, birthday parties, or end-of-unit celebrations.

Book Pairings for Ocean-Themed Fun

Pair your Jello cups with ocean books to turn snack time into story time

“Mister Seahorse” by Eric Carle – A beautifully illustrated introduction to sea creatures and parenting in the ocean
“The Pout-Pout Fish” by Deborah Diesen – A rhythmic, fun story that’s great for preschool and early elementary
“Way Down Deep in the Deep Blue Sea” by Jan Peck – A playful underwater adventure that aligns well with the candy sea creatures
“Commotion in the Ocean” by Giles Andreae – Full of rhymes and fun facts about ocean animals
“Ocean Life” by Jill McDonald – A nonfiction board book for younger learners to explore real-world marine life

Reading about the ocean while enjoying ocean-themed snacks strengthens comprehension and makes connections between fiction and hands-on experience.

Fun Ways to Customize

Every ocean cup can look a little different—here are some creative twists:

• Use whipped cream on top to mimic waves or foam
• Add a Swedish fish poking out of the whipped topping like it’s jumping out of the water
• Freeze them slightly for a cool summer treat with a popsicle texture
• Include shell-shaped candy or small edible pearls for a more detailed sea scene
• Make a dairy-free version using vegan gelatin for allergy-friendly classrooms

You can also send these cups home in to-go containers for family night or party favors.
