1. To draw a crab, first draw its body. Use a small square to draw the body, and then use a small circle to connect the pliers. Note that the pliers should be larger, so that they are exaggerated and vivid. Use the pliers to draw on both sides, leaving space in the middle for eyes. 2. Now let’s draw the eyes. Use two lines to draw a circle, and the eyes will appear easily. You can draw another small circle in the eye before drawing the eyeball, which will make it more vivid and detailed.

3. Start drawing the side feet. Use relatively straight fold lines to draw the small feet. Pay attention to two lines to draw one foot, so that the inside can be painted. 4. Add a big mouth to the crab to make it more lively and interesting. 5. Finally, just use a bright red watercolor pen to color the crab. You can use dark red for the mouth. I used orange for the tongue, so that there will be some color changes and it will look better. The step-by-step method of drawing a simple crab is: the body is round, with big claws on both sides of the eyes, and more claws on both sides of the body. Finally, add color to the crab. The reasons why crabs walk sideways are: the chest is wider from side to side than front and back, the steps are on both sides, the front foot joints can only bend downwards, not outwards, and the knees cannot bend backwards. These physical characteristics can only walk sideways.
