Step 6: Under Squirtle's head and on either side of the body, draw two shapes as guides for the arms. The shape on the left is similar to a stretched-out oval. The guide on the right is similar minus the top, more like a long U shape.
Step 7: Below the body, draw a couple of shapes as guides for Squirtle's feet. The shape of the feet are similar to upside-down letter Us with a line across the opening. The upper left side of the foot on the right is missing because it's behind the body.
Step 8: On the left side of the body, draw a long arc as a guide for Squirtle's tail. The line begins below the left arm and extends down to the left foot.
Step 9: That’s it for the initial sketch! You have the basic Squirtle shape. Now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 10: Darken the shape of Squirtle's eyes. Draw a small oval on the top part of each eye to represent glare. Below the glare draw a bigger oval and shade it in for the pupils. Above the eyes, draw a couple of small lines for extra detail.
