This is not your father's Monster Blood
The last Monster Blood book in the original series of Goosebumps, and also the final book in that entire run.
Andy has gotten her hands on some more Monster Blood! Sort of. This stuff is blue, and instead of growing, it reproduces. It also takes the form of slimy slugs with razor-sharp teeth. The plot is basically Gremlins if Gizmo was also evil.
It is the last of the nineteen original series books that was not adapted into the 1995 TV series. It wasn't even referenced during the Monster Blood event in Goosebumps HorrorTown.
It provides examples of:
- Adoring the Pests: Andy thinks the blue Monster Blood creature is cute and pets it. The creature ends up multiplying when it drinks water and soon the town is overrun with blue Monster Blood creatures. Making matters worse is the fact that while the first creature starts off as docile and friendly, the resulting creatures get aggressive as it multiplies. The more creatures pop up, the more aggressive they are.
- Aesop Amnesia: Let's face it. From what we read from the last two books of the saga, it would be rather redundant at this point to go on about how Andy still doesn't learn how dangerous the Monster Blood is when she decides to use some on Conan the second time, especially since Evan tells her the exact same reason why it's a bad idea as he did in the sequel.
- Belligerent Sexual Tension: Evan and Andy seem to have a kid version of this.
- Blob Monster: The blue Monster Blood is more animalistic than the green stuff, but is still mostly slime.
- The Bully: Conan's only purpose in this story, as usual, is to pick on Evan more even when Kermit is the one who causes problems for Conan. And in the end, there are four of him!
- Butt-Monkey: Evan, as usual. This whole story involves him getting one of the sleeves of his sweater pulled by Conan, getting bitten by one of Kermit's tarantulas, zapped by Kermit's electric fence, having his ear pulled by Conan until it swells, burning his lips after eating spaghetti spiked with hot sauce, and attacked by the Monster Blood creatures. Not to mention about to be attacked by a gang of Conans at the end.
- Covered in Gunge: When the first blue Monster Blood creature multiplies, it explodes, sending blue slime splattering on the protagonists. Andy’s hair and Kermit’s glasses are covered in the mushy stuff.
- Didn't Think This Through: When he first rounds up most of the blue creatures, Kermit goes to hide them somewhere in his house. When Evan asks him the next morning where he hid them, he replied his basement bathroom. Evan points out in shock that a bathroom contains plenty of sources of water, which the monsters consume to multiply. Kermit tried to counter this by saying that they're in bags, only for Evan to snap at him that they're in PLASTIC bags, which the now teethed monsters could chew out of in seconds.
- Gender-Blender Name: Andy, whose real name is Andrea.
- Green Is Gross: Averted — the Monster Blood is blue this time.
- I Am Not Weasel: The blue variant of Monster Blood actually turns out to be a genetics experiment Gone Horribly Wrong which the creator dumped inside an empty Monster Blood can when he couldn't find a proper container.
- Misplaced Retribution: As usual, Evan is on the receiving end of this under Conan's wrath every time Kermit would do something to anger Conan.
- Negative Continuity: Monster Blood III ended with Evan still shrinking, but here he's perfectly fine. Perhaps Kermit managed to tweak his formula.
- Puppy Love: Evan and Andy is the most obvious example in the series, with some blatant (adolescent-style) Belligerent Sexual Tension and for the most part behaving like a romantic pairing throughout the series, though never actually becoming an Official Couple.
- Series Continuity Error: Monster Blood II established that Andy is staying in Atlanta with her aunt and uncle, as her parents are off elsewhere for a year. But in this book, Andy mentions going to her father's lab in town.
- Too Dumb to Live: You'd think that Evan and especially Andy would learn by the fourth book of the MB series that the Monster Blood is extremely dangerous, yet they still use it at an attempt at vengeance.
