Prehistoric Island

Prehistoric Island is a rare sea event in the Third Sea and the only place that gives Dinosaur Bones and Dragon Eggs. Sail into Sea Danger Level 6 and it may appear, much more often if someone on your boat carries a Volcanic Magnet. On the island you play the Volcano Event: 5 minutes to keep the volcano's pressure down while Lava Golems try to smash the relic. The bones and eggs craft Dragonheart, Dragonstorm, the T-Rex Skull and the Dino Hood, and one egg unlocks the Draco race. Each egg also has a tiny chance to hand you a Dragon fruit, East or West.

Quick questions about Prehistoric Island

No. The lava on top of the volcano kills quickly even with Magma or Tiger equipped. Drink Lava Potions before the event instead.
No. One magnet anywhere in the sea exploration group raises the odds for everyone, and the driver does not have to be the one holding it. The Sentinel plan is the exception: there each of the 2 to 8 players carries one.
It is the common short name for Prehistoric Island, so a message like "PH spawned" means the island is up.
It is one of the Admin Abilities, named "Draconic Incandescence of the Vermilion Firmament". See Admin Abilities for the others.
Before Update 31.3 a bug hid the volcano pressure and the relic health. Without the meters, players guarded the relic completely and destroyed the lava as soon as it spawned.

How does the Volcano Event work?

The event lasts 5 minutes and has two jobs at once: close the volcano cracks, and keep the relic alive. Open Steps for the order, Rules for what counts.

How the Volcano Event works

Steps
Step
Start
What happens
Touch the Fossil Ancient Relic. A cutscene plays and you have 5 minutes.
Step
Pressure
What happens
Cracks open on the volcano. Hit the glowing orange spots with a Destructible Physics move (one that breaks terrain) to close them and keep the pressure down.
Step
Golems
What happens
Each closed crack sends a meteor down, and a Lava Golem appears where it lands. Golems run for the relic or a player.
Step
Relic
What happens
Stop golems reaching the relic while you close cracks. Both jobs run at the same time.
Step
Win
What happens
At zero, bones fall near the relic, and the eggs spawn if the relic held up (see Rules). The Prehistoric Cave opens.
Step
Fail
What happens
If the relic reaches 0 health, the message "The relic has been fully destroyed" appears and everyone who took part dies.
The Volcano Event starting on Prehistoric Island in Blox Fruits

The Volcano Event begins.

How do you beat the Volcano Event?

Any move that breaks terrain can close a crack, and your stats make no difference. What decides it is who covers the golems and who covers the volcano.

Volcano Event strategies for groups and solo players

Group
Job
Split in two
Plan
One team lowers the volcano pressure, the other guards the relic. With only two players, the one with the bigger area moves takes the volcano.
Job
Pressure team
Plan
Flying fruits cover the cracks fastest: Eagle, Light, Magma, Phoenix or Dragon. Awakened Dough climbs with Scorching Donut (F).
Job
Golem team
Plan
Use stuns, area damage and moves with no wind-up, so you can dodge and pull golems away. Hitting them toward the beach keeps them off the relic. A sword-wielding Buddha user fits well.

What do you get from Prehistoric Island?

You leave with Dinosaur Bones and Dragon Eggs. Open Craft for what they make, Sources for the other materials, and Odds for the amounts.

What is the Prehistoric Cave?

The Prehistoric Cave sits below the Fossil Expert and stays closed until a Volcano Event is finished. Draco players use it to get V4 (the Race Awakening, see the Race Awakening guide) and upgrade it, and only one player per island can enter and take the Trial of Flames. A black door in the cave opens only for the Draco race.
