Zombie School

 Zombie School was the fortieth book in the Give Yourself Goosebumps gamebook series. It was preceded by Scary Birthday to You! and followed by Danger Time.

On the cover was an image of a zombified student in a school cafeteria. The student zombie had pale, corpse-blue skin, and was drooling. The tray he was carrying had macaroni and cheese, green beans, a corn muffin, and a milk carton.

It was released in November 1999 and was 144 pages long.

Plot
You are transferred to an exclusive boarding school in Nevada, where all of the children are very quiet. During homeroom, your teacher Miss Simms warns that any student breaking rules will be given demerits and sent to the Detention Wing, where the school makes an example of "bad" students. One such student enters the room and you are shocked to see that he looks like a zombie. While Miss Simms is out of the room, you steal the monocle she wears, but discover that when you look through it there are hidden brainwashing messages all over the walls and many more of the students look like zombies. The reader must then decide whether or not to put back the monocle before the teacher notices it's missing.

Story A

You put the monocle back, but what you've seen is enough to convince you that something is seriously wrong at the school. The story focuses on your efforts to escape from the school and/or alert the authorities, as the zombies start to close in on you.

Story B

You keep the monocle. Before Miss Simms can find out who took it, the bell rings and it's time for class. You pick four classes from a list of six and have to survive them. This storyline is similar to the setup found in ''Shop Till You Drop ... Dead! and You're Plant Food!''

Side Story C

You end up in the forest with the "Runaways", a group of other kids who have escaped from Ranewash School. You must then help them decide what to do in order to destroy the school. This storyline can be reached through either Story A or Story B.

Bad Endings

 * You call the police to help you. An officer comes to collect you, and you notice his class ring from Ranewash, meaning he is a zombie too. He takes you to jail so you can't tell anyone the truth.
 * You escape town on a bus, but the movie played on the bus brainwashes you. You will go on to turn your family and everyone else you know into zombies.
 * You're in a forest, being chased by an enormous guard dog. You decide to climb a tree to escape the dog, but then a panther comes through the treetops and eats you.
 * The Runaways give you a flare and challenge you to scare away the dog. However, the flare fails to ignite, so the dog gets you.
 * You're sedated and all your organs are removed.
 * You smash a transmitter that's going to be implanted into your skin, but tentacles sprout from the transmitter and strangle you. This is a built-in mechanism so the transmitter's host can't escape.
 * While searching outside for your missing hall pass, you are ambushed by a guard dog.
 * A teacher writes an instruction on your forehead for the other students to attack you. You try to wash it off in the bathroom, but they catch you and beat you to death.
 * You try to run past guard dogs and escape through the emergency exit, but you're not fast enough, and they catch you.
 * Max turns out to be a spy and lures you and the other runaways back into the school, where you are chained up in the Detention Wing.
 * Miss Pierce mind-controls you into spying on your fellow students.
 * Alternatively, you disobey her order, but this causes your head to explode.
 * You and Ally test out the scents that control the dogs, but you accidentally combine the scents to make purple, causing the dogs to attack you.
 * Kate's braces interfere with the brainwashing machine, so everyone comes under her control. She forces you to make her ice cream from scratch, starting with milking the cow.
 * You're brainwashed and forced to write a letter to your parents, saying that you want to stay at the school and never come home. Then you stay at Ranewash and work forever, even during vacation.
 * Forced into being a kitchen assistant for the next four years until graduation.
 * You go to the soccer field when you shouldn't be there, and are killed by giant lawnmowers.
 * Because you tried to pull the brain-sucking octopus's tentacle free from your head, your brains leak out. This leaves you literally mindless, and you go back to class to obey with the other zombies.
 * Electrocuted on an electrified fence.
 * You missed your chance to take the test in detention, so you are stuck in the Detention Wing forever. This is stated to be the worst ending in the book.

Good Endings

 * You find the right scent to control the dogs, and use them to chase away the teachers. You are now trying to find a way to return the other students to normal.
 * You're wearing metal when you enter the brainwashing machine, which somehow reverses its effect so that the teachers obey you. You take charge of the school and put an end to all homework.
 * You overwhelm the brain-sucking octopus so much that it shrinks away into nothingness.
 * You and Kate are caught and brainwashed, but you are so delighted to obey Ranewash that it is presented as "The Happiest End of All."
 * You become the youngest news anchor in the country, and your report gets Ranewash School closed down. You broadcast subliminal messaging that deprograms all the zombies.

Trivia

 * This book is a little different to the others in the series; some of the poor choices will not imediately lead to a bad ending, but rather issue the reader with a varied number of "demerits".  If you have too many by the time you reach a certain point in the book, it could lead to a bad ending.
 * Although the series is usually gender-neutral to accommodate the reader, this book mentions in some places that "you" are male.
 * Despite the cover image, you don't go to lunch at any point.
 * The title of Why I Quit Zombie School is ostensibly a spiritual successor to this book, although they are set in different schools (Ranewash School vs Romero Academy.)
