Baldi is a little boy who is afraid of his teacher because she is a scary woman who looks like a ghost. She is very tall and thin, and has a creepy smile. She always wears a black gown and has a bag full of bats. She will often call the students in the classroom bad boys and girls, and will punish them for no reason.

The teacher has a special room in the school where she teaches her students. She likes to make them suffer, and she also likes to play pranks on them. One day, she saw Baldi in the classroom, and she asked him to sit in the front row. She then told him that he was going to teach a lesson to the whole class. He was afraid, and he said that he wanted to leave. But the teacher told him that he had to stay and learn the lesson. He was afraid of her, and he started to cry. The teacher then started to tease him and make him suffer.

Baldi has two friends, a girl named Barbie, and a boy named Steve. They are friends of Baldi, and they are always trying to help him. One day, he decided to play a prank on his friends and teacher.
