Among the various food items available in LEGO Fortnite, the Slap Juice can work wonders as it adds three Hearts, two minutes of Stamina Regeneration, and five Hunger levels. Engaging in activities and battles can reduce your Hearts, Hunger, and Stamina levels. Since the game is teeming with things to build, animals to pet or fight, and a lot more, it is important to keep eating to replenish said levels.
