Doctor Fred Edison is an eccentric scientist who lives with his bizarre family in his centuries old home, somewhere in New England. One day, his pets, genetically engineered tentacles by the names of Green and Purple, come across waste being dumped into a creek. While Green stays away from it, Purple takes a taste of some of it and is mutated, giving him limbs as well as superhuman intelligence. Driven mad by the sudden power rush, Purple sets off to conquer the planet and replace the human race with tentacles. However, Fred captures them, and thinking Green may have been exposed as well, regretfully decides he must euthanize them. Fearing for his life Green sneaks out a telegram to his old friend, nerdish college student Bernard Bernouli. Bernard, bent on rescuing Green, sneaks himself, his med student girlfriend Laverne, and roomate, Hoagie, off campus and drives to the mansion, where Purple and Green are both set free and Purple escapes to go on a rampage.

Hoagie finds dry spaghetti in the Colonial-era mansion kitchen. Italian cuisine did not make it to the United States until the 19th century. Therefore, it's highly unlikely someone would have pasta in their kitchen around this time. See more »


Laverne: This is all your fault Bernard.
Dr. Fred: Behold, children! The Chron-O-John!
Hoagie: Doc, can't you just send Bernard?
Dr. Fred: No, you must all go to increase the odds that one of you will make it there alive.
Bernard: Has any people even been hurt in this thing?
Dr. Fred: Of course not! This is the first time, I never tried it on people.

User Reviews

Hilarious! Just Hilarious!
7 July 1999 | by Quint-6See all my reviews

One of the greatest of all time. Entertaining, with a great plot, and an excellent follow up to the video game Maniac Mansion. "WKRP in Cincinatti's" Richard Sanders is great as Bernard Bernouli, and gives him the vocal life robbed of him in the video game. Penny Roberts Hope is equally charming in her dual role as the crazed medical student Laverne and kinky nurse Edna Edison. Also of note is Denny Delk, who does a great job as the stereotypical vaudeville villan Purple, a disembodied tentacle. For any kid, for anyone who is a kid at heart, this is recommended to you.
