Hank sacrifices himself by dropping an electrically charged broadcast tower onto Hoolar, electrocuting her and her brood. Dale and Martha brace and cling to the small remnant of land as the island sinks, sharing a final embrace.

Timeline questions answered

Attack of the Crab Monsters Timeline Explained: Your Questions Answered

When does it happen, and why in that order? The questions people ask about the chronology of Attack of the Crab Monsters (1957): time jumps, flashbacks, cause and effect between scenes and the correct order of events, each answered with spoilers.

Q1

Why could the crabs speak with human voices?

The giant crabs had absorbed the minds of their victims, including McLane, the leader of the previous expedition. This allowed them to telepathically communicate using the voices of the people they had eaten, which is why Martha heard McLane calling to her.

Foreshadowing: Martha first hears McLane's voice calling to her on the second night, hinting at the crabs' psychic abilities before the team fully understands what happened to the previous expedition.

  • telepathy
  • crabs
  • mc lane
  • minds
  • voices
  • communication
Q2

How did the crabs become immune to weapons?

The crabs developed cellular mutations from Bikini Atoll radiation exposure, making them virtually indestructible. Their cell structure changed in a way that standard weaponry could not penetrate or harm them effectively.

Foreshadowing: The scientists initially attempt to fight the monsters with conventional arms but quickly realize their weapons are useless against the mutated creatures.

  • radiation
  • mutation
  • weapons
  • immunity
  • crabs
  • cellular
Q3

Why were earthquakes happening on the island?

The two giant crabs were tunneling beneath the island, systematically undermining and eroding the land itself. These tunnels caused the earthquakes and landslides that progressively destroyed the island throughout the story.

Foreshadowing: Carson falls into an earthquake pit during tremors, and the scientists later connect the seismic activity to the crabs' underground activity.

  • earthquakes
  • crabs
  • tunnels
  • island
  • destruction
  • landslides
Q4

What was Hoolar's plan for the mainland?

Hoolar, the surviving intelligent crab, intended to travel to the mainland with her fertilized eggs once the island was destroyed. She planned to feed on human minds and spread her offspring to populated areas.

Foreshadowing: The crabs' stated goal of breeding and spreading to populated areas is revealed early through the scientists' discoveries about the previous expedition's fate.

  • hoolar
  • mainland
  • eggs
  • reproduction
  • breeding
  • spread
Q5

How did the scientists kill the first crab?

The team placed an explosive device in a cave where one of the giant crabs was located. When detonated, the explosion caused a massive overhead rock to collapse, crushing the monster's head and killing it.

Foreshadowing: After discovering the crabs' plan to reproduce and destroy the island, the scientists pivot to stopping the mating pair as their primary defensive strategy.

  • explosive
  • cave
  • crab
  • kill
  • rock
  • crush
Q6

Why did the seaplane explode?

The seaplane exploded for no apparent reason during the attempt to return to the mainland. The film presents this as an unexplained tragedy that further strands the scientists on the island, though the cause is never explicitly shown or explained.

Foreshadowing: The explosion occurs shortly after the deadly attack on Tate, suggesting the island's corrupted environment may have affected the plane, though this is never confirmed.

  • seaplane
  • explosion
  • crash
  • stranded
  • island
Q7

What happened to the previous expedition on the island?

The previous scientific expedition was completely killed and eaten by the two giant crabs. The crabs absorbed their bodies and minds, gaining their knowledge and ability to communicate telepathically using their voices.

Foreshadowing: Journal entries from the prior team mention killer worm-like creatures, which the scientists initially misinterpret before discovering the truth about the crabs.

  • previous expedition
  • killed
  • crabs
  • eaten
  • mc lane
  • journals
Q7

How did Hank sacrifice himself to stop Hoolar?

As the last remains of the island sank into the Pacific, Hank triggered an electrically-charged broadcast tower to topple onto the giant crab Hoolar. The electrocution killed both Hoolar and her unfertilized brood, stopping the threat but costing Hank his life.

Foreshadowing: With the island collapsing and no other options available, the survivors must make a desperate final stand against Hoolar and her reproductive plans.

  • hank
  • sacrifice
  • electrical
  • tower
  • hoolar
  • electrocution
Q9

Why did Martha hear McLane calling to her?

Martha heard McLane's voice because the giant crabs had consumed McLane and absorbed his mind. The crabs can communicate telepathically in the voices of their victims, using this ability to lure and manipulate the current expedition.

Foreshadowing: This telepathic call occurs on the second night, before the team understands the true nature of the threat they face.

  • martha
  • mc lane
  • voice
  • telepathy
  • call
  • lure
Q10

What were the crabs' overall intentions on the island?

The crabs intended to breed and spread from the island to populated mainland areas. Their goal was to feed on human minds while propagating their species, making them an existential threat beyond just the isolated island.

Foreshadowing: This motivation is revealed through Hoolar's final telepathic communication, where she expresses her desire to reach the mainland with fertilized eggs.

  • crabs
  • breed
  • spread
  • mainland
  • eggs
  • mind feeding
