The episode begins where Gumball and Darwin knock on the nurse's door at Elmore Junior High in an attempt to skip gym class. On their way down the hall, they meet Coach, the new gym teacher.
At gym class, Gumball was doing push-ups and a large amount of organ's tears were poured out of his sweater or shirt and Gumball got weak. Coach then orders Jamie to do a cartwheel, and Jamie did it wonderfully. Gumball tries to do the cartwheel, but he did it so fast that he landed with a thud. Gumball does a trampoline to bounce higher, but ends up crashing up the ceiling.
At the school cafeteria, the tired and injured students complained about how hard it was in gym class. Jamie then bursts into the cafeteria, and orders the students to beat it, but Gumball still stood there. Jamie was about to hit Gumball in the face, but Coach stopped her and made her apologize to Gumball. Jamie says she's sorry and she will be friends, which shocked him, and the rest of the students were shocked too.
The next day, Jamie then encounters Gumball and Darwin. Gumball tries to convince to Jamie that she doesn't have to be a bully anymore, but Jamie shoves him in Darwin's mouth, and tells the classmates about the school going in history. Out of school, Gumball and Darwin discussed the moments of Jamie torturing the students. They then see Coach and Jamie riding home in their car. Gumball and Darwin went after them.
After running and encountering a bunch of dogs along the way, they arrived at Jamie's house, where Jamie's car arrived home at the same time. Jamie's father welcomes them home. Coach then reveals she is a woman, which shocked Gumball and Darwin again.
