Lay your seashell on green construction paper and draw a head coming from the top, 2 arms coming from the top sides, 2 legs coming from the bottom, and a tail from the back.
Cut out your turtle body and set aside.
Use your paintbrush and green paint to paint the top of each seashell green and let dry.
Glue your green turtle shell to the turtle body.
Glue two googly eyes onto the turtle head. Cut out several tiny trapezoids and hexagons and glue them to the top of the turtle shell.
