Step 1: Begin with the narwhal's horn by drawing a triangular cylinder.
Step 2: Connect the body to the horn by drawing long "S" shaped line on one side, and a curved line on the other.
Step 3: Add the eyes to the body, just below the horn, by drawing two circles.
Step 4: Below the eyes, draw a curved line for the mouth.
Step 5: Add the fins by drawing a sideways "V" shape on either side of the body below the face.
Step 6: At the end of the body, draw two connected "V" shapes for the tail fin.
