The monster I created

My monster must be very ugly and he can spitfire to the people. He would have a green body,  a big blak eyes and plant's mouth. He will eat the children to make alive at this world. He will have the sticky skins. he has the most scared voice. He always appears at the middle night. He will be strong and move fast. He can change his body shape and to hide in the crowd. You will never know when he will come and how he come to your side. I will call it as "blood evil”.
