Update 71 of Steal a Brainrot went live on October 17, 2026. According to the community wiki's Update Log, it introduced the Halloween event Spooky Scary Skeletons, seven new brainrots and a round of income changes for eleven existing ones. This page collects those changes in one place, with the numbers the wiki lists and a clear note wherever the wiki is silent.
The information comes from the wiki's Update 71 page and the individual brainrot pages, not from first-hand play. Several brainrots in this update are no longer obtainable, and the table below says which.

The Spooky Scary Skeletons event
The wiki describes Spooky Scary Skeletons as a Halloween event that starts on 10/17/2026 and has no confirmed end date. It activates every hour on weekends and every two hours on weekdays. During the event, skeletons can give different traits to brainrots; the most common is the normal skeleton and the rarest is the Witch Skeleton, listed at a 5% chance.
Three brainrots come from the event, each with an approximate spawn rate on the wiki:
| Brainrot | Rarity | Income | Cost | Spawn chance (wiki) |
|---|---|---|---|---|
| Co Co Co Sahur | Secret | $1.7M/s | $525M | about 20% |
| Chicken Zombie | Secret | $5.5M/s | $1B | about 10% |
| Skelly and Coffy | Secret | $155M/s | $100B | about 0.5% |
One caveat: the wiki notes that the Spooky Skeleton board was deleted on October 24, 2026, visible in a leak from that date. The event page does not state that it ended, so the exact status is unclear. Check the in-game board before planning around it.
All seven new brainrots
| Brainrot | Rarity | Income | Cost | How to get it (wiki) |

Notes from the wiki pages:
- Arca Bros is a baby Arcadragon next to a baby Arcadopus. Its income and cost match Dragon Cannelloni, and the wiki calls it the best DLC brainrot so far.
- Medusini and Demonini is listed as coming from the Haunted Fuse, which is covered in the Haunted Fuse guide.
- Cobra Gelato and Slushi Huski both come from MerchShop DLC codes. Slushi Huski is the first Husky brainrot.
- Chicken Zombie is a Zombie Tralala baby riding a chicken, and the wiki gives its release as October 17, 2026.

| Los Mobilis | $22M/s | $8.5M/s | $1.4B | Unobtainable (Witch Fuse) |
The pattern: six machine-made brainrots jumped to high income, while five others lost income. Because most of the buffed brainrots can no longer be obtained, their value now depends on what players already own. The values page tracks trading numbers separately.
