The ClueFinders 5th Grade Adventures: Secret of the Living Volcano is a computer game released in June 7, 1999.


The ClueFinders embark on an oceanic expedition aboard a ship captained by Leslie's grandpa, Captain Clark. While searching the sea floor in a submarine, Joni and Santiago come across a sunken ship. Inside the ship are mysterious stone tablets with carvings on them. Joni and Santiago return to Captain Clark's ship and show him the tablets they found. Santiago thinks they may be a clue to why so many ships have been disappearing in the area. One of the ship's crew calls out to Captain Clark the ship is approaching an island. Captain Clark remarks the island isn't on any of his charts. Suddenly, a tsunami approaches the ship, threatening to capsize it.

Later, Santiago and Joni wake up on the island's shore, isolated from the rest of the ship's passengers. As they try to comprehend what happened, a quake goes through the island. Santiago realizes that they are next to an active volcano that is going to erupt soon. Leslie and Owen contact Santiago and Joni with the video phone, and explain that they trapped in an underground chamber somewhere, where there are thousands of the same kind of artifacts Joni and Santiago retrieved earlier. Joni and Santiago set out to explore the island and find Owen, Leslie, and the rest of ship's passengers.

As Santiago and Joni start exploring, they meet several island residents who all claim that the island is alive. For centuries, no one has been able to leave the island. Many of the villagers were descended from people who shipwrecked on the island during the time of the Revolutionary War, and still dress and talk as people did in that time. Every time the islanders tried to leave in boats, they were mysteriously pushed back by the waves, and since they were cut off from the rest of the world, they had no way to call for help. Furthermore, people on the island have been steadily disappearing, seemingly swallowed up by holes in the ground that move on their own. The ClueFinders discover that the key to solving the island's mystery could lie in the CrypTiles, artifacts with strange writing scattered throughout the island. The CrypTiles are needed to complete challenges near the top and bottom of the island.

After Joni and Santiago complete the challenges near the top and bottom of island, they are transported inside the volcano. They fall down a passageway into a chamber where they reunite with Owen and Leslie. Suddenly they hear a loud sound, and a strange creature with a green hand tries to grab them. They quickly run in different directions. Leslie, Owen, and LapTrap end up in a chamber with a large chasm. Joni and Santiago end up in a strange room with a lot of containers filled with a green, jelly-like substance. They are startled when they suddenly see Captain Clark in one of the spheres. Joni and Santiago get trapped inside one of the spheres themselves, and as they look around, they realize that many of the spheres contain people who got trapped on the island. They are all perfectly still and staring straight ahead, as if locked in some form of stasis. Joni and Santiago alert Owen, Leslie and LapTrap as to what's going on, when they suddenly an ominous, beast-like shrieking sound.

Meanwhile, at Owen and Leslie's location, Owen comes to the conclusion that they are actually on a spaceship. A robotic face on a wall starts speaking to them, and informs them that they must create a bridge sequence in order to access the first biosphere containment tank. Leslie and Owen discover that aliens have secretly been using the island to trap and contain various species of animals, and humans, for the purpose of raising them on their planet. The aliens wish to harvest human brains for sustenance, since human brains are considered a fine delicacy on their planet. Leslie and Owen find a way to release the specimens using using the computer guarding to them to simulate a predator-prey relationship that would allow the species to thrive on the aliens' planet.

After Owen and Leslie release all of the specimens, including the people who were captured, the aliens finally catch up to them and attempt to seize them. All of the people flee into a nearby room and close the door. The ClueFinders find themselves looking at a control panel with four large buttons. Leslie advises not to push them, since they have no idea what the consequence will be, but Owen points out that they have nothing to lose. One by one, they each push the button in front of them, which cause different effects to the island. One of them initiates a launch sequence, and another causes a door to open up to the sea outside. One of the islanders that they met prior arrives at the door in a ship, presumably Captain Clark's after it was patched up, and all of the people quickly get on board. Leslie was the last to push a button, which initiates a tsunami sequence. As they all escape on the ship, a giant wave from the tsunami pushes them far out to sea, just as the volcano on the island erupts, and the entire island breaks apart and sinks into the sea. For a moment, the water is entirely still as the ClueFinders look on in wonder. Then, a gigantic spaceship shaped like the island emerges from the water, and in a flash, it zooms away. Joni remarks that no one will believe what happened, but Santiago insists that they will, since they should still have a couple of CrypTiles left in Joni's backpack. However, when they look at Joni's backpack, the bottom is completely torn. Leslie wonders where the last CrypTiles went, and Captain Clark replies that they are somewhere out there, in the depths of the ocean.
