There are several caves in Poptropica.
Shark Tooth Island
The ancient ruins are to the right of Main Street. To get the missing translation page, push the big block to the right and climb the vine, then jump left onto the roof.
Time Tangled island
The cave is at 831 AD. Get the barrel of gunpowder at the right side in 1593 AD (Great Wall of China). Click the cave to blast it open. The Golden Vase is at the bottom left, but you have to go the long way around, up and right, then back to the left.
Nabooti Island
The ice cave is at the Mountains of the Moon. Let the second goat butt you up to the trail, then avoid the rocks and slippery snow. Beat the old man at mancala to enter the cave, where you get the cell phone and the Red Jewel.
The Blue Jewel is at Blue Nile Falls. Help the woman cross the falls, then go far right to the cave behind the bush on the small rock.
Astro Knights Island
The cave is in the volcano on the Fire Planet (X-83 Y-20). Jump across the rocks to reach the volcano (for the last jump, when both rocks are moving down). Inside, avoid the rush of hot air by hiding in the holes and nooks where it doesn't reach.
Mythology Island
Enter the realm of Poseidon using the starfish from his statue in the museum. Go left and swim out to the water maze. Go right, down, and left to reach the Hydra's cave. The Giant Pearl is just outside.
