While pulling up at an autbody car shop, the only thing that's missing is the worker. She calls out his name several times, and figures no one's there.
Donna didn't know, but as she was trying to take Danny's seat belt off, Cujo was waiting for his next victim.
As Cujo came up on Donna and Danny, he made a big thug when hit himself against the car door. Donna thought he had knocked himself out. She thanked god.
Cujo jumped on the car and made a big thud. Danny stated that "CUJO" was the monster in his closet. A viscous substance dripped on Donna's arm, including blood and slobber
Cujo came up to Danny's side of the window and threw himself up on the car. Donna rapidly grabbed the wheel to roll up the window and Cujo finally gave up and took his head out. Danny was horrified.
As Donna started the car to drive away from the auto body shop, Cujo, once again came up on them without noise. Danny was still horrified as hey drove away and would still forever be terrified of dogs.
