Circle Sponges: Use a black marker to trace circles onto the sponge. Cut out 2-4 circles, depending on how many fish you want to create.
Prepare Paint: Pour green, yellow, red, and blue paint onto a paper plate. These will be the bodies of your fish.
Sponge Painting: Dip the sponge circles into the paint, creating one circle each of yellow, red, and green, and two circles of blue. Press them onto a sheet of paper to make the fish bodies.
Fish Details: Cut out triangles from the construction paper for the fish tails and fins. Make sure the colors match the bodies of your fish.
Bring to Life: Once the paint has dried, glue on the googly eyes and draw a smile on each fish with the black marker. Add bubbles and waves around the fish using blue and black markers to complete the underwater scene.
