Yellow Horseshoe Balloon

The Yellow Horseshoe Balloon is an accessory that grants immunity to fall damage, increases jump height by 75%, and grants a double-jump. The height of the first jump is increased from 6 blocks to 10½ blocks, while the double-jump's height is increased from 15 blocks to 26½ blocks, reaching a total of 37 blocks with both jumps.

Jump height is instead reduced by 15% when underwater, reducing your total underwater height from 27 blocks (8 + 19 from Sandstorm jump) to 22 blocks (7 + 15 from Sandstorm jump).

Tips

 * The double jump is more similar to the Rocket Boots in function than to the Cloud in a Bottle: the button must be held down for maximum effect. However, letting go early will forfeit the rest of the jump's height instead of being able to use the full height in small bursts.
 * Unlike the Rocket Boots, the Sandstorm jump provides a speed boost when used, which can be used to quickly turn around while retaining some speed.
