Cloud in a Bottle

The Cloud in a Bottle is an accessory that can be found in Gold Chests in the Underground and Cavern layers. When equipped, it allows the player to double-jump. The second jump increases the maximum height the player can reach by 5 blocks, for a total of 11 blocks.

Trivia

 * The Cloud jump goes the lowest out of all the double-jump accessories in the game, but it is also arguably the easiest to get.
 * Redigit confirmed that the Angel Statue was originally intended as a placeholder sprite for the Cloud in a Bottle.
