Cloud in a Bottle

The Cloud in a Bottle is an equippable accessory that allows the player to perform double jumps, by hitting the jump key again in midair. It will also allow the player to perform a jump while falling, even if the fall did not result from a jump, making it one way to avoid fall damage. It is found randomly in all types of chests, including in Dungeon chests. Its Quality is 1 as of version 1.0.4 (3 in earlier versions). A cloud jump offers an additional jump of 3.5 blocks, for a combined jump height of 9.5 blocks. The effect is not stackable using multiple Bottles, ie. two bottles do not allow two 'cloud jumps'.

Rocket Boots stack with this item, allowing for a triple jump; the first double-jump activates the Cloud in a Bottle, and the second activates the Rocket Boots.

Shiny Red Balloon affects the double jump height of Cloud in a Bottle, increasing it from 3.5 blocks (7 feet) to 7 blocks (14 feet), for a grand total of 17.5 blocks (35 feet, including the initial jump).

If the Flippers are equipped and the player performs multi-jumps underwater, the player will not be able to perform a double jump upon exiting the water as the multi-jumps performed underwater count as a double jump (even though the double jump animations and sound effects are never shown).

For a silly effect, you can use the Cloud in a Bottle at the same time while using the Whoopie Cushion, as this will look like a fart.
