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 is 1 block shorter than the first jump, but it still increases the maximum height the player can reach by 5 blocks, for a total of 11 blocks.

Trivia

 * Redigit confirmed that the Angel Statue was originally intended as a placeholder sprite for the Cloud in a Bottle.
