Step 1: Begin by drawing a lemon shape for the body.
Step 2: Add some details to the face, by drawing a circle for the eye with smaller circles inside for reflections. Add a line for the mouth with some teeth along it. Draw a curved line for the chin, and some tiny c-shapes for the scales.
Step 3: Copy the front legs at the back of the body to make the back legs.
Step 4: Next we can draw the fins. Draw two triangles below the body, and one triangle on top.
Step 5: Finally, draw the tail. Draw a shape a bit like a heart at the end of the body.
