Pet Simulator 99 events

October 2026 was a chain, not one festival. Update 96 was Hatch Wars, 97 was Blood Moon, 98 was Diamond Mountain, 99 was PSX Classic, and 100 was Halloween Games on 31 Oct. The Yeti people search is the Diamond Mountain world boss from 17 Oct, not its own season. Blood Moon is a repeating sky, not a map tile.

• Halloween Games — the live update, Forge, Treats, clan battle.
• Diamond Mountain — Yeti boss, 17 Oct 2026.
• Blood Moon — about 10 minutes, roughly every 2 hours.

The Update 100 note explicitly keeps Halloween Games pets untradable until 7 Nov. The leaderboard’s scoring cutoff is 6 Nov, and the Ender Clan Battle runs six days. Neither deadline establishes a universal event end. Christmas and older archives stay on the studio’s event index.

Match the reward to its event

Start with the newest patch date, then open the page for the mechanic you need. Use Halloween Games for the Forge and Treats, Diamond Mountain for the Yeti, and Blood Moon for the repeating luck window documented in Update 97. An old egg remaining in the public database does not prove that its event is still open. Keep an event’s launch date, contest duration, and reward trade-unlock date separate. The next Saturday update is a schedule reference, not proof that every older activity ends on that day.
