PocoStick

As you can see, PocoStick! Makes Traveling lot fun and easier!

GIF: The player bounces repeatedly using a Poco Stick, held in hand or worn on the back. Holding the jump key increases bounce height with each landing; the stick renders under the player's feet while airborne, and the player's normal walking animation freezes during the bounce sequence. Each landing triggers a short bounce animation and sound effect.

JEI (Just Enough Items) recipe viewer showing the two crafting recipes for the Poco Stick. Both use the same 3x3 shape: a wooden stick in the top-left and top-right corners, an iron ingot in the center-left, and a slime block at the bottom-center. The only difference between the two recipes is the top-center item — the first uses a regular piston, the second a sticky piston. Both produce one Poco Stick.
