Should I draw the strange dark object?

In Singapore, my sometimes lunchtime places are in the Korean enclave. There is a little mischievous kid who darts in and out of a cafe I am at. I try to speak little Korean with her. Though amused (she must wonder what is this large dark object making familiar sounds), she hardly has patience to listen to a full sentence before she darts out to slay another monster. The kid came by and left me this drawing. Now, I am wondering what to draw for her.
