 * Mallet (60 G): cures amnesia;
 * Maiden's kiss (500 G): cures toad;

Permanent items
These items can be used repeatedly in battle and don't get used up. They are considered by some a prototype of the more famous Summons that are introduced in Final Fantasy 3 and became a staple of the Final Fantasy series.
 * Gaia drum: found at the bottom of Tropical Island, bought at the top of it; it casts "Earthquake 10"; it is actually used up after about a hundred usages;
 * Wyvern: found right before the Cyclone; it casts "Blaze 7"; it is also a key item.

Consumable items
Mostly won from defeated enemies or sometimes found in chests.

They can be used once only, unless stated otherwise.

Key items
Items necessary to advance in the plot, few of them have uses throughout the full video game.
 * Ring: shows the world map; push B and Select, as in Final Fantasy 1;
 * Canoe: allows to travel on freshwater (rivers and lakes, but not open seas);
 * Snowcraft: allows to travel on the glacier;
 * Wyvern: use it in battle to breath fire on the enemies.
