How to describe the tiger in the kindergarten class?

Round eyes, wide open; There are some beards around his mouth. When he opens his mouth, he will show big teeth as sharp as a sharp knife. The tiger, full of food and drink, lay lazily on the ground and fell asleep, with his round head resting on his front legs and his eyes half open and half closed, and he didn't know what he was thinking. The black stripes on the tiger's forehead look like a striking "king" written with a brush.
