“Remember that bad thing we saw? It looked just like this. This is bad.”

The Movie



The film begins when an earthquake hits Mexico, resulting in the overnight birth of a new volcano. Sent to study this phenomenon are geologists Dr. Hank Scott and Dr. Arturo Ramos. En route to the village of San Lorenzo, the two men happen upon a destroyed house and a totaled police car. They find the dead policeman nearby, as well as an abandoned infant. They take the infant to San Lorenzo and give it to some friends of its (now missing) parents, and are welcomed by the village's priest, Father Delgado. In addition to the disappearances of locals and the destruction of their homes, there have been wholesale slaughters of livestock and strange roars in the night. The villagers believe the culprit to be a demon bull and have been pestering Delgado for divine assistance. Undaunted, Hank and Arturo begin their geological survey as members of the Mexican army, led by Major Cosio, arrive in San Lorenzo to begin disaster relief efforts. Hank meets and falls in love with local rancher Teresa Alvarez and makes friends with a young boy named Juanito.


The volcano erupts again and the true culprits behind the disappearances and deaths are revealed as giant prehistoric scorpions. After attacking a staff of telephone repairmen, the scorpions turn their attention to San Lorenzo itself, with the guns of Major Cosio's troops having no effect on them. The next morning, the scorpions have returned to their underground lair (which, in addition to the scorpions, is home to giant worms and spiders), leaving the authorities to seek the help of renowned entomologist Dr. Velasco. It is up to him, Hank, and Arturo to figure out a way to either destroy the scorpions or seal off the entrance to their cavern home, before more innocent lives are lost.

Despite collapsing the cave entrance, the giant scorpions make it to the surface and destroy a train, killing some passengers before fighting amongst themselves. In the end, one scorpion, the largest of the group and presumably the alpha scorpion, kills all of the smaller ones, making it the last scorpion alive, and it heads for Mexico City. Hank and Arturo come up with a plan to lure it to a stadium where the military is waiting with tanks and helicopters. Using a truckload of meat from a butcher shop, they manage to lure the scorpion into the stadium where the military's weapons are again proved useless against its armor. However, Hank manages to finish it off by using an electric cable attached to a spear and shooting it into its throat, which is its only vulnerable spot. After destroying several tanks and choppers, the scorpion is finally, and fatally, electrocuted.[1]


  • The sounds of the scorpions are the same sounds as the ant chirps in Them! (1954).
  • The trapdoor spider that attacks Juanito in the scorpions' underground home is one of the original models left over from the famous deleted spider sequence in King Kong (1933)
  • That giant worm with the "octopus-like arms" seen in this film is a prop from the unused spider pit sequence from the original King Kong (1933).
  • While filming the stop-motion effects at Tepeac Studios, O'Brien and Peterson were assisted with miniature set construction by Ralph Hammeras, who was at the same studio filming the visual effects for The Giant Claw (1957).
  • Many of the screams heard are stock sound effects that can also be heard in many Republic movie serials.
  • Willis O'Brien and Pete Peterson began filming the special effects of this film in a large remodeled dressing room at the Tepeac Studios in Mexico City, but when money became tight they finished the picture in Peterson's garage in Encino, California.
  • The volcano shown at the beginning was Paricutin which erupted in 1943 and was active for about a decade.
  • At the conclusion of the scene where Hank and Arturo have arrived in the village for the first time and after Hank has given the baby Manuel to the Parish Priest and are preparing to get out of the Jeep a bird can be heard chirping followed by a cat meowing. Although there are special effect sounds and music added to the audio track it would appear that they were otherwise recording raw audio as they filmed with little post-production work to clean up environmental noise.

The Episode

Host Segments


An SOL tribute to Mexico

Prologue: The Bots throw a party, for Joel.

Segment One (Invention Exchange): Joel makes a giant party favor and then Dr. Erhardt starts to show their invention before realizing it's exactly the same thing as Joel made. A lab accident with a "cold fusion Walkman" mutated Dr. Erhardt in to an alien-type creature, while Dr. Forrester becomes a skeleton. Forrester tries to soften the blow by claiming their invention was actually a salve to cure their "condition".


Gypsy as a scorpion

Segment Two: Joel and the bots present a madcap tribute to Mexico

Segment Three: Crow and Tom discuss human nature, unaware that Gypsy has become a scorpion monster

Segment Four: Crow and Tom put on a puppet show and discuss stop-motion animation, correcting the earlier mistake regarding Ray Harryhausen designing the effects when it was actually his mentor, Willis O'Brian.


A mutated Dr. Erhardt

Segment Five: Reading letters


  • When introducing the film, Dr. Forrester states that the effects are by Ray Harryhausen. They are, in fact, by Harryhausen's mentor, Willis O'Brian and animator Pete Peterson.
  • The scorpion/spider model that appears in Host Segment Four is made from a Masters of the Universe Spydor toy. The box for this toy (presumably the same one) was later used for the Freak Out kit in Experiment #410 (as revealed in the first Poopie! volume).

Running Jokes

  • Joel and the Bots clap whenever Dr. Hank Scott's name is spoken.
    • Or is it for Dr. Arturo Ramos and the sudden fancy Spanish accent accompanying it?

  • "It’s the Cisco Kid!"

The Cisco Kid was created by O. Henry in the 1907 short story “The Caballero’s Way.” In this tale, he is an outlaw who kills and robs along the Texas-Mexico border. However, when the character was adapted for other media, he became a hero. The first of twenty-seven films was released in 1914; the last in 1950. In 1942, a radio series began that ran for more than 600 episodes before its end in 1956. A television series—the first to be produced in color—ran from 1950-1956. Comic strips and comic books were published off and on between 1944 and 1967. In 1972, the band War released a popular song titled “The Cisco Kid.” The character hasn’t done much of anything since the western genre petered out except for a 1994 TV movie starring Jimmy Smits as the title character and Cheech Marin as his sidekick, Pancho.

  • "Hey, it’s Dale Evans, and I thought she was stuffed. –Mounted."

Dale Evans (1912-2001) was an actress, singer, and the third (and last) wife of singing western star Roy Rogers (1911-1998). She co-starred with Rogers in more than two dozen films and in NBC’s 1951-1957 The Roy Rogers Show (a 1960s version of the show didn’t last very long). In 1953, she published a book titled “Angel Unaware”, which was about her and Roy’s daughter Robin, who died before the age of two from complications related to Down’s Syndrome. Her openness and advocacy changed public attitudes toward the mentally disabled. Roy Rogers’ famous horse, Trigger, is frequently thought to have been stuffed after his death in 1965. In fact, a plaster likeness was made and his preserved hide was stretched over it. In taxidermy, this is known as “mounting.” Trigger was on display in the Roy Rogers and Dale Evans Museum, first in Victorville, California, and later in Branson, Missouri, until it closed in 2009. In case you’re wondering, Dale’s horse was named Buttermilk; he was also mounted and displayed at the museum after his death.

Robot Monster is a 1953 science fiction film often regarded as one of the worst films ever made, featuring, as it does, a man in a gorilla suit with a skull mask wearing some sort of diving helmet while destroying the world with a bubble machine. It was featured in Show 107.

  • "The weather started getting rough. The tiny ship was tossed."

A couple of lines from “The Ballad of Gilligan’s Isle,” the theme song of Gilligan’s Island, the 1964-1967 CBS sitcom. It was written by Sherwood Schwartz and George Wyle. The first season version was performed by The Wellingtons; later seasons were sung by The Eligibles.

  • "Are those foam hats? I told you to wear mouse ears."

Presumably a reference to the mouse-ear hats originally worn by the Mouseketeers on The Mickey Mouse Club, which first aired in 1955. The hats were designed by Disney artist Roy Williams, who also played “Big Roy,” the adult Mouseketeer on the show. They are sold at the Disney theme parks, with space for the child’s name to be embroidered on the back, and now come in a dazzling array of varieties and colors other than basic black.
