Balloons

Balloons are accessories that increase the player's jump height by 33% and jump speed by 30%, increasing the height that the player can jump from 6 blocks (12 feet) to ~10½ blocks (21 feet), effectively a ~75% boost. However, it oddly reduces jump height when underwater, from 8 blocks (16 feet) to ~7 blocks (14 feet). Balloon upgrades offer various extra abilities, such as an extra jump or immunity to fall damage.
