Step 1: Bats are the only rodents with wings. Start your bat with a circle for the head.
Step 2: Connect an ellipse to the bottom quarter of the circle to form the body.
Step 3: Draw the left wing as a curved line running from the top of the body and a zig-zag line running from the bottom of the body. Connect both lines together in a point to form the tip of the wing.
Step 4: Draw the right wing in the same manner, but flipped.
Step 5: Draw the ears as pointed ellipses protruding from the top left and right of the head.
Step 6: Draw the eyes as shaded circles, but leave white dots on the top right of each circle. Draw the mouth as a thin "D" turned on its side.
