How to draw Cute Mermaid Drawing for Kids | Easy Step-by-Step Sea Creature Drawing and Coloring

What you need

Adult supervision required, cardboard base or shoe box lid, clay (air-dry or polymer follow package directions), coloring materials optional, glue (strong craft glue), non-toxic paint, paintbrushes, recycled bits (cardboard bottle caps fabric scraps small plastic pieces), sculpting tool or spoon or toothpicks, water cup and paper towel

Step 1

Lay out all your materials on a flat table so you can see everything and work easily.

Step 2

Imagine where your sea creature lives and choose one special adaptation it needs like speedy fins camouflage or glowing spots.

Step 3

Shape a clay body by rolling and molding the clay into the size and form you want your creature to be.

Step 4

Make fins tail or extra body parts by rolling flat pieces of clay or cutting and shaping recycled bits.

Step 5

Attach each fin or recycled part to the body by pressing gently and blending the edges with your finger or tool.

Step 6

Create scales or skin texture by pressing a tool or a patterned recycled item repeatedly onto the clay surface.

Step 7

Add eyes by pressing small clay balls or beads into the head and make a mouth or gills with a toothpick or sculpting tool.

Step 8

Place your creature on the cardboard base and arrange recycled pieces as plants rocks or coral for its habitat.

Step 9

Let the clay dry or bake it following the exact directions on the clay package so your creature becomes hard.

Step 10

Paint your creature and its habitat with base colors using brushes and water as needed.

Step 11

Let the paint dry completely before touching your creature again.

Step 12

Add final details like highlights spots tiny patterns and glue on any loose recycled decorations.

What can we use if we can't find modeling clay, beads, or a cardboard base?

If you don't have modeling clay use air-dry clay or homemade salt-dough for shaping in the clay body step, swap beads for small pebbles or tightly rolled foil for the eyes in the add-eyes step, and replace the cardboard base with a stiff cereal-box panel or thin wooden board for the habitat.

My fins or recycled parts keep falling off after drying or baking—how do I fix that?

When attaching fins in the attach-each-fin step, score both surfaces, add a little water or clay slip, blend the edges firmly with your finger or a tool, and for air-dry clay push a toothpick or thin wire into the joint as an internal anchor before drying.

How can I change the activity for different ages so it's safe and fun for everyone?

For preschoolers simplify steps 3–6 by giving pre-rolled bodies, large recycled shapes, and stickers for eyes instead of beads, while older kids can add wire armatures, intricate texture tools during the scale-texture step, and use polymer clay with careful baking in the drying/bake step for durability.

What are some ways to enhance or personalize our fantasy sea creature after painting?

After painting in the paint-your-creature step, glue tiny LED lights into glowing spots powered by a coin-cell on the cardboard base, varnish with clear sealer for shine, and add a handwritten habitat card describing its special adaptation and pretend behavior.

Facts about ocean habitats and adaptations

♻️ Upcycling trash into art helps keep plastic out of oceans and teaches creative reuse.

🐠 Fish fins, scales, and colors often evolve for camouflage, speed, mate attraction, or warning signals.

🎨 Many artists combine clay with recycled bits like bottle caps, wire, or fabric to make mixed-material sculptures.

🐙 Octopuses have three hearts and can change color and texture to camouflage or communicate.

🌊 Scientists estimate we've explored only about 5% of the ocean — plenty of space for imaginary sea creatures!

How do I make a fantasy sea creature from clay and recycled materials with my child?

Start by brainstorming the creature’s habitat and adaptations—shallow reef, kelp forest, or deep sea. Shape a basic body from air-dry clay, then add fins, scales, and texture using extra clay or recycled pieces like cardboard and egg cartons. Let the clay dry, attach recycled elements with child-safe glue, then paint with acrylic or tempera. Seal if desired and encourage your child to name the creature and explain its adaptations.

What materials do I need to make a fantasy sea creature craft?

You’ll need air-dry or modelling clay, child-safe paint (acrylic or tempera), paintbrushes, and a nonstick work surface. Gather recycled materials—cardboard, egg cartons, bottle caps, plastic lids—and glue (PVA or hot glue used by an adult). Also have scissors, toothpicks or sculpting tools for texture, markers and optional glitter, plus a clear sealer if you want to protect paint. Supervise scissors and hot glue with younger kids.

What ages is this fantasy sea creature activity suitable for?

This craft suits children roughly ages 4–12 with adjustments. Ages 4–6 enjoy simple shaping and painting with close adult supervision for small parts and scissors. Ages 7–9 can add more detailed fins and textures and use basic tools. Ages 10–12 can plan adaptations, mix media, and work more independently. For younger kids, pre-cut recycled pieces and use non-toxic modelling clay; older kids can try air-dry clay techniques.

What are the benefits of making fantasy sea creatures with kids?

Making fantasy sea creatures boosts creativity, fine motor skills, and storytelling. Children practice planning and problem-solving while designing adaptations for imagined habitats, which reinforces basic science ideas like camouflage and buoyancy. The project encourages communication and collaborative play, and painting helps color recognition and patience. Displaying finished creatures builds confidence and pride in their creative work.
