Four SpongeBob SquarePants-themed islands have made their way to Fortnite's Creative mode, which has filled fans with hope of additional crossovers in the future. Although Battle Royale gets most of the fan attention, Epic Games is constantly working on all of its Fortnite modes to make sure that the game doesn't stagnate but continues to grow and get even better as time goes by. Fans who were there when Fortnite Creative was still known as Playground mode will be fully aware that it's one of the modes that has seen the most radical changes.
