The blue marks represent the ability Trinity Jump Sora, Donald and Goofy bounce on the floor, shaking treasure loose from somewhere above them, or accessing higher levels. The first obtained in the game and by far the most common, Trinity Jump ( トリニティジャンプ, Toriniti Janpu ?) is learned after defeating the Guard Armor boss in Traverse Town. In Kingdom Hearts Final Mix, this Mark is moved under the arch below the manor, so that it is still accessible after the battle, but it will still cause the shed to disappear when activated. In that version of the game, the mark causes a small storage shed to disappear when activated, but the mark disappears once the manor is destroyed in the battle against Oogie Boogie. Almost all Trinity Marks can be activated at any point in the game, with the exclusion of a single Red Trinity Mark in Oogie's Manor in the original Kingdom Hearts. Certain Trinity Marks must be activated to progress through the story, but most are optional and only required for completing Jiminy's Journal.
The friends learn five different Trinity commands throughout their journey, each with a different color, as well as the combat ability " Trinity Limit". This will cause the trio to perform an action respective to the mark's color, which usually results in opening a new path or revealing a rare treasure. In Kingdom Hearts, Sora can activate the "Trinity" ability while standing on a Trinity Mark while Donald and Goofy are in the party.
