Overview

The Cave Island is a tiny island in the Second Sea. It has three chests: a silver (on one side of the large main cave), a gold (on the grassy top), and a diamond (behind a partial wall in the upper room).

Trivia

• The Cave Island does not have an official name. • It is not accessible from Portal's World Warp ability. • There used to be a Poneglyph on Cave Island, but it was later removed in Update 13. • The Cave Island does not have its own background music, but the sea background music plays instead. • Like the Remote Island and Jean-Luc Island, The Cave Island is not really considered an island and using a Miracle onto this island will not make the boat land onto the sea. therefore, The player can drive the boat into the cave island, and land it in the island's ground.
