Uncharted Islands

Uncharted Islands are islands in Dragon Quest Monsters: Joker 1 that you sometimes go to instead of going to the island you were trying to go to. There are several types of uncharted islands.

Slime Islands
Slime Islands are inhabited by slimes, she-slimes, and behemoth slimes. They are often searched for, as they are the only way to obtain behemoth slimes which are useful in synthesis.
