Step 11: Use the shape on the bottom side of the main circle as a guide to draw Squirtle's mouth. Make the top sides pointier and give the top line a slight bend to form a beak. Above the mouth, draw two small slits for Squirtle's nostrils.
Step 12: Draw the rest of Squirtle's head using the main circle as a guide. Darken the shape of the circle. The right side of the head should come closer to the eye to create the cheek.
Step 13: Draw Squirtle's arm on the left side by using the initial shape as a guide. Darken the base of the shape and draw two triangle-like points at the end for the fingers.
Step 14: Use the shape on the bottom as a guide to draw the left foot. Darken the top part and again draw three triangle-like points at the bottom for Squirtle's toes.
Step 15: Draw the top part of Squirtle's shell by using the original oval as a guide. Draw a couple of wavy lines between the hand and foot to create the edge of the shell. Draw a line on the lower left side for the markings on the shell.
