The cover art depicts a dinosaur skeleton reaching over an exhibit barrier. The skeleton appears to be that of a Tyrannosaurus Rex.
Talk About a Jawbreaker!
Help! You're trapped in the Hall of Science. And a mad Super Computer wants to keep you there forever. Escaping is the ultimate challenge. Because in this book there’s only one way out. That's right. Make one mistake—and you're cake.
The Hall of Science is filled with tools you can use to protect yourself against a terrifying T-rex, a rampaging robot arm, and other enemies. But look out! The giant mutated germ will make you sick. And the pendulum will hypnotize you...to death!
The choice is yours in this scary GOOSEBUMPS adventure that's packed with over 20 super-spooky endings ― but only one way out!
You are on a school field trip to the museum, "The Hall of Incredible Science". You lag behind the others to play a video game exhibit based on your favorite action film when a message appears on the screen asking for help. You then encounter a murderous sentient computer called the Super Computer, who claims you now know too much to leave and manipulates the entire museum to become a death trap. Unlike most of the Give Yourself Goosebumps books, this book uses dice during several choices, and the end result explains whether the previous choice "worked" or not. The book is longer than the others and is mostly divided into sections.
The following list includes all the items the reader can possibly encounter and use in the story. Keep in mind that several items have conditions such as one-time-use only, requiring another item in exchange, triggering an enemy encounter, or possibly being completely useless.
- Fire Extinguisher
- Space Glove
- Gift Shop Key
- Noise Bomb
- Smoke Bomb
- Stink Bomb
- Electric Motor
- Jet Pack
List of endings
There are thirty-nine bad endings and only one good ending.
While still in keeping with the usual choices, many endings are caused by either poor dice rolls or incorrect item usage.
- Attempting to combat the Visible Man, you decide to throw your noise bomb at him. Once the bomb detonates the loud explosion ends up deafening you. As you try to get your bearings, the Visible Man strangles you.
- You decide to risk dashing past the Visible Man, but he easily grabs you.
- You are covered with fire ants and trying to swat them off causes them to bite you more. You eventually succumb to their poison.
- Your virtual plane turns not to have a landing gear, which will cause your plane to crash while landing.
- Inside the space capsule, you choose to press the red button, which causes the capsule to crash through the ceiling and land at the cafeteria where it's infested with aliens. There you discover The Hall of Incredible Science is an alien experiment and while you pass the test, the aliens still want to eat you.
- You continue to struggle unstrapping jet pack from the astronaut display because you want to keep your space glove. In your haste, the jet pack is accidentally started flies off without you, and the animatronic arm grabs your neck.
- The germ keeps expanding until it fills up an entire room. You suspect that the germ may never stop growing, which will cause the entire world to become sick.
- You try to open a door, but it electrocutes you.
- You use a stink bomb against the Visible Man, and — while the bomb subdues the Visible Man — you are also suffocated by the bomb.
- A helicopter crashes into you and its propeller blades decapitate you.
- You enter the elevator, and it begins to rise. However, it doesn't stop, and it smashes you into the roof.
- Because you failed to hit its power button with the boomerang twice, the robot arm finally reaches and grabs you by the ankle. It twirls you in the air before hurling you into a wall.
- A poor dice roll determined that you were too slow to outrun the Giganotosaurus skeleton. Just as you reach the doors to escape, the fossil grabs your shirt by the teeth and drops you into the tar pits.
- Your plane malfunctions while you are in the air. Even if this is a simulation, you are unsure if you will live or die.
- You flow into the electric current of the Tesla coil. While you are trapped in the coil, you are also broadcasted onto millions of televisions.
- Your braces are attracted to a large magnet. You are pulled onto the magnet, and you are unable to remove yourself.
- You are unable to avoid the mosquito and it begins draining blood from your leg.
- You try to hit the mosquito, but it avoids your attack. It begins draining blood from your arm.
- You run for the door in order to avoid the robot arm. You trip and the robot arm grabs and strangles you.
- Your helicopter crashes and you are crushed.
- You try to grab a cable, but it is coated in grease. You slip and fall down the elevator shaft.
- After the simulator crashes, the door opens. The mosquito flies in and begins draining blood from your chest.
- You're thrown back by an electric shock, which gives the mosquito ample time to begin draining the blood from your chest.
- A large tidal wave created by the Super Computer catches up and washes you into the sewer.
- After futilely trying to throw the boomerang, you try defeating the mosquito with your hands. The mosquito latches onto you and sticks you in the arm with its tube. As the insect drains your blood, the boomerang comes back just in time to hit you in the head before you go unconscious.
- Multiple small, mechanical dinosaurs attack you at once, and they eat you.
- You escape the model helicopters that were chasing you by using the jet pack, but you dropped your glove in the chase. So just as you touch the door, you are electrocuted.
- You try to squash the mosquito in a clap, but it dodges and impales you.
- You think that the snake won't be able to bite you while you're wearing the space glove as you reach for the laser. However, the snake instead bites your arm slightly above where the glove ends.
- The Giganotosaurus skeleton is approaching you, so you decide to shine your laser on it. The laser does nothing and you remember too late that the fossil doesn't have any eyes to blind with it.
- You try to make a smoke bomb, but just as you finish you notice that the chemicals react unstably. You begin to figure that the instructions and ingredients were tampered with shortly before the bomb explodes in a poisonous cloud.
- You input the incorrect Crash Code and the Super Computer, now in the form of a dragon, captures and forces you to rebuild a castle which will take about a century.
- You can't prevent yourself from being hypnotized by a spiked pendulum, so it kills you.
- The robot arm has followed you from the Space Travel Room and grabs your leg. Once it dangles you in the air, the model helicopters swarm and lacerate you.
- You try to use a noise bomb against a snake, but you soon remember snakes don't hear very well.
- In Virtual Reality, the dragon Super Computer teleports you in a dungeon with the intent of keeping you there for the rest of your life.
- You and the Nature Scouts become lost in the Maze of Mirrors forever.
- Not wanting to risk the PDA being destroyed in a mechanism's gears, you reach inside a mechanism to receive the device early. However, your hand is caught and grinded on in a difference gear.
- You defeat the Super Computer by using the correct Crash Code, while you are in virtual reality. A tiny elf girl, who turns out to be a PDA, decides to "reward" you by transporting you to a jungle film set. She explains that the sequel to your favorite movie, "Operation Buzzard", is being filmed and that you are acting in it as the hero's actor yourself. As you get ready for the first scene, escaping a stampeding elephant, you realize you never read the script and have to wing your performance. As you weigh in your options, the story ends with you uttering "Oh no! Here we go again!".
- With forty different endings, this book has more endings than any other Give Yourself Goosebumps book.
- A guide to completing this book was included in Checkout Time at the Dead-End Hotel on pages 139 and 140.
- Several choices are dependent on what items the reader has collected during their adventure, and to make matters worst, picking up an item will often trigger an event that can kill the reader without the correct item, so the reader needs to do things in a specific order. Some items do nothing, and choosing them can hinder progress as they prevent you from getting all the useful items.
- One of the later dice related choices determines how fast the reader can run during a chase scene, and the higher the number the slower he or she will be (making it harder to escape). As an additional challenge, each item the reader still has is added to the dice numbers.
- Because of how the book is written, certain things will happen differently depending on what order you do things; e.g. if you visit the room with the giant mosquito before you attempt the flight simulation, the mosquito will be around during the simulation.
- Some of bad endings contain a hint for next time; usually hinting at what item the reader should have used.
- There is a maze on one floor, but the reader doesn't get to play with it like most Give Yourself Goosebumps books. Instead, the majority of that section is dedicated to choosing which direction to turn.
- It is possible to lose all but one item you have collected so far in the book and never get them back without cheating. To make matters worse, the one item you get to keep has already exceeded its usefulness.
- On section #221 (because there are sections, not pages), the reader has to find the correct Crash Code by using an abacus correctly.
- There are four ways to reach section 137.
