"You" and a friend are visiting your mother in the labs of her employer, the esteemed scientist Dr. Eeek, who is willing to pay you to help in some of his experiments. However, those experiments will have strange consequences.
The Deadly Experiments of Dr. Eeek provides examples of:
- Advertised Extra: The "Vampire Gorilla" on the front cover shows up in exactly one ending, and nowhere else in the entire book.
- All Just a Dream: One of the endings have you waking up and realizing the while adventure is just a dream. But then your mom reminds you she's still going to bring you to her lab. Here We Go Again!, then...
- Animorphism: Two of the endings sees "you" turned into a dog permanently.
- Bittersweet Ending: In one ending, you get turned into a dog, but at least you managed to return home safely and live as the new family pet!
- Didn't Think This Through: Hiding under the operating table turns out to a poorly thought out plan, as the sheet covering the table doesn't completely cover the reader. The other hiding place, Dr. Eeek's office, is an equally bad idea, as it is Dr. Eeek you are hiding from, and he is obviously going to go into his office. Fortunately, the latter ending reveals that you were just having a nightmare.
- Gratuitous Laboratory Flasks: On the cover, artist Mark Nagata saw fit to include the crazy lab-coated monkey mixing green chemicals together in test tubes, while all manner of other bits and bobs of lab glassware is visible (none of which appear in the book itself).
- Half-Human Hybrid: You encounter one of these, a German Shepherd/human hybrid, in one path of the story.
- Here We Go Again!: Two endings conclude with this phrase. One is where you wake up to find that this whole experience was a dream, but your mother's dialogue implies that the same event will happen again for real this time. The other is where your friend Sam (who in a sense, got you into this whole mess by wanting to explore the labs) runs off to do some more exploring in the same lab that he and you could have either died in, or worse.
- Horrible Judge of Character: Yeah... at what point is it a good idea to trust someone named "Dr. Eek"?
- Malicious Monitor Lizard: One ending features a Komodo dragon casually biting you, triggering your death from the bacteria in its saliva so it can take its time eating your remains.
- Morton's Fork: While trying to escape from Dr. Eek, one path has you trying to remember if you go left or right to get back to the reception area. If you go right, you run into a "vamporilla"- a gorilla-bat hybrid- and get killed by it. If you go left, you make it back to the reception area but can't open the solid steel door due to it being knobless and after a string of events, you get sprayed with deadly sleeping gas by Dr. Eek's assistant.
- Mutagenic Food: Eating the dog food in Dr. Eeek's lab turns you into a German shepherd.
- Never Trust a Trailer: One of the blurbs of this book implies the half dog half kid is an enemy who is "after you" - in actual fact he's a good guy, and even gives you an item which necessary to surviving the book at one point.
- Rodents of Unusual Size: You can be cornered by a giant rat in one ending.
- Shout-Out:
- The Strange Case of Dr. Jekyll and Mr. Hyde is mentioned early in the story. Fitting, since it's classic literature about another Mad Scientist.
- One scenario have you coming across a sentient, singing frog, but you're unable to convince anyone to believe you. So, Michigan J. Frog?
- Tickle Torture: At one point, you will be asked a question that tests your knowledge of the main Goosebumps series. If you answer it incorrectly, you will be tickled to death by chimpanzees.
- Too Many Halves: One bad ending has Dr. Eeek discovering the reader after they try to hide under the poorly covered operating table. The deranged doctor then turns the reader into part kid, part dog, and part basketball.
- Uplifted Animal: In one scenario, you found out the chimpanzees in the lab are sentient now, and they're studying humans instead of the other way around. And it goes without saying you risk becoming one of their test subjects in a bad ending...
