Fall Island is located on the lower right quadrant of the map. The surface includes an earthy terrain topped with orange grass and green and dark green trees that surround the Bunker Door in the center of the island.
The player can find a family reunion of rigs and a button that reads "click 2 get all cheevos :3", along with buttons claiming to give frenzy buff, free money and inf prestige.
Trivia
Fall Island was added in the Spring Cleaning update, released on June 16th 2023.
The Fall Island had the most amount of edits, starting with dark green grass and dark green trees, then going fall gold, a bunker appearing, then having an upper section added, then the Roblox mansion, no changes have happened after besides minor tweaks.
The Fall Island is home of the Witch NPC, where you'll (soon) be able to buy the seasonal Halloween candies with Tokens.
The Bunker serves no use, there is nothing in there, do not investigate!
