Search For The Needle Alien Event
What changed
A September 7 gameplay recording opens on an Alien Cheese limited event and shows three balances in the broader update context: ordinary money, Gems and an additional alien/event currency.
The same recording redeems ALIEN and receives 200 Gems + 200 Alien Coins before returning to the normal haystack loop.
How it connects to Chapter 2
Chapter 2 is already alien-themed: a trapped Alien, puzzle panels, colored crystals and a UFO ending. The event therefore is not just a random shop skin layered over an unrelated story beat.
Alien Coins
Do not describe Alien Coins as Gems. They are shown as a separate balance. Some current update footage discusses additional ways/codes for event currency, but not every promised code in live-chat commentary was already available at the time of recording.
What to watch next
The official Roblox page advertises an Index + Pets content event for September 12. Those systems are not live in current sessions, so there is no Pets or Index page yet.
