Players squish Rigellians that spawn in Springfield 1 every 5 minutes, with a maximum of 80 (only 50 appear on screen, then as tapped, the remaining 30 will slowly spawn if full), and receive 3/2/5, and 1 of the phase currency in a friends' town. You can only squish 90 Rigellians a day in friends' towns. Treat Bags and Donuts can also be obtained from squishing Rigellians.
You can also receive Grem-Alien Eggs, which can be used in players' towns (10 maximum) to release Grem-Aliens which after 4 hours if not squished by the other player, the player receives 4/4/2 If the Grem-Alien is squished, both players receive 2 of the phase currency.
In the friends menu, in the medal icon, there is a leaderboard which tells the player how they rank amongst their friends, with Grem-Alien squishing and spawning. Each Grem-Alien you squish earns 15 points. Each one you spawn in a friend's town earns 10 points, and if the friend doesn't squish it within 4 hours you'll get an additional 20 points. If they do squish it in time, your friend gets 15 points.
The player receives Treat Bags from sending Kids, More Kids, Toughies, the Squeaky Voice Teen and Witch Marge on an 8 hour task (16h for premium characters) to "Go Trick or Treating"1, which rewards either a Bronze Treat Bag, a Silver Treat Bag, or a Gold Treat Bag. Premium characters earn either a Silver or Gold Treat Bag. The player can find Chocolate Bars, Gummy Bears, Pumpkins, Rotten Eggs, Candy Corn and Broken Fences, to craft items, Nails to upgrade the weapon, event currency, Ammo, a Rigellian Shrub, a Human Test Subject, a Spooky Wall, 2 and a Grem-Alien Egg.
The player can receive Ammo which is used in friends' towns to shoot down UFOs, which have a 25% chance of appearing which the player can receive rewards for. Ammo is obtainable through Treat Bags and from squishing Rigellians or Grem-Aliens. The Ray Gun also rewards 1 every 8 hours.
Ammo can also be bought in the Store.
5 Ammo - 15
UFOs can also be shot down for a cost of 5 each, if the player does not obtain any Ammo at that point.
The Rigellian Hunting License can be bought for 90, which gives an extra 1 of the phase currency (2 in total) for squishing Rigellians in a friend's town.
There is an Autumn theme to Springfield. Trees have changed to autumn colours/stripped of leaves, leaves falling appear on screen, rivers are dark blue with occasional tentacles coming out of them. There is a slight darkening at the edges of the screen.
The Store and inventory have changed. In The Store, the items have been split into sections:
The game will also recommend items which appear on the first page of the The Store next to the "Treehouse of Horror XXV" image.
The Krustyland Store and inventory have also changed. In The Store, the items have been split into sections:
A Facebook button has appeared in the bottom right corner of the friends screen.
Visibility requirements have changed. Instead of being visible but locked when you haven't reached the building's level, now the game won't show them until you're within a level or two. For example, the Power Plant buildings become visible when you hit level 10 but aren't available until you hit level 11 (and reach the associated quest to unlock them).
A few of the Clash of Clones decorations have continued to be available for purchase: the Hot Air Balloon, Flaming Torch, and Chicken Coop.
Characters were removed again from the Krustyland Goers character group. They were added with the Level 43 update, removed with the Clash of Clones update, and then added back with the Level 44 update. This character group isn't used for tasks.
The Spooky Tree and Dead Tree was added to the Trees Group.
Placing a Beach Chair now requires you to have completed the quest Squidport Pt. 1.
Cletus' 12 hour task to "Dig Through Garbage" now requires an unoccupied dumpster.
Barbarian Castle, Castle Recycle and Boxingham Palace now earn 90 and 10 every 4 hours. Barbarian Castle's task is "A Chill Place to Bro Out", Castle Recycle's is to "Host Green Party Meetings" and Boxingham Palace's is to "Visit Rat Kingdom". They are all now storable, and the Barbarian is attached to the Barbarian Castle, so if you store the Barbarian Castle the Barbarian will be stored with it.
Medieval Banners, Barbarian Statue, Hot Air Balloon, Hay Cart, Stock, Catapult, Flaming Torch, and Windmill can now be placed in Krustyland, they give 10 Kitsch points each.
A premium default job award for a 45 second task has been added, which earns 5 and 2.
The regular job award for a 3 hour task now earns 75 and 7. It used to earn 70 and 7.
Suzanne the Witch and Count Burns are now Premium characters.
