Step one: first draw a wide-mouth bottle. 
Step 2: Then draw some irregular circles inside the bottle. Children who don’t know how can ask their mothers to help. 
Step 3: Then draw small ovals like animal ears on top of the circle you drew. Draw two on each circle. 
Step 4: Next draw the eyes and mouths of the little chinchillas. In order to give the little chinchilla different expressions and demeanor, you can draw the little chinchilla’s mouth into different shapes. 
Step 5: Use a wood-colored pen or a different bottle-colored pen to draw the lid on the bottle. 
Step 6: Finally dye the bottle and chinchilla. Just like that, the bottle was filled with many little chinchillas.
