The Gym Gains event in Plants Vs Brainrots challenges you to submit Brainrots based on their weight to unlock rewards. Running from January 3 to January 10, 2026, this event adds a fresh way to play with 25 milestones full of exclusive items and rare Brainrots.
First things first, here’s a quick overview to get you started:
- The event runs from January 3, 2026, at 3:00 AM PT to January 10, 2026.
- You must unlock Central Island by reaching Rebirth 1 and paying 1,000,000 Cash.
- Submit Brainrots within a specific weight range that increases with each milestone.
Here’s how to jump into the gym gains event
To access the event, you need to unlock Central Island. This happens once you hit Rebirth 1 and spend 1 million Cash. After that, head to Central Island and find the gym-themed area called Planet Freshness. Use the portal near the Brainrot spawn conveyor to enter. You’ll see a red submission button : this is where you submit Brainrots that meet the weight requirements.
What’s special about submitting Brainrots by weight?
Instead of submitting any Brainrot, the event asks for ones within a certain weight range. It starts with Brainrots weighing between about 5.5 kg and 11.5 kg. Each time you submit a Brainrot, the required weight range goes up by 0.25 kg on both the minimum and maximum ends. So the next submission might ask for Brainrots between 6.0 kg and 12.0 kg, and so on.
By the time you reach the final milestones, you’ll be submitting Brainrots weighing around 18 to 24 kg. This means you’ll want to keep an eye on your Brainrots’ weights and pick the right ones carefully.
Tip: Use the search bar in your inventory and type a number within the required weight range to find eligible Brainrots quickly.
Submit your Brainrot to King Lemon, who will "bench press" it to count toward your progress.
How do you move through the 25 milestones?
Every Brainrot you submit that fits the weight range moves you one step forward on the milestone track. There are 25 milestones total, each unlocking a reward. As you progress, the weight requirements increase, so you’ll need heavier Brainrots to keep going. This keeps the event challenging and fun.
What rewards can you get?
The event offers a mix of cash, seeds, potions, exclusive Brainrots, and other useful items. Here’s a quick look at some milestone rewards:
| Milestone | Reward |
|---|---|
| 1 | $15.5 B Cash |
| 4 | Orcalero Orcala, 4x Frost Grenade, and $7.79 B Cash |
| 5 | Sunflower Seed, Shiny Expansion Pack, and Las Tralaleritas |
| 10 | Dragon Fruit Seed, Frost Grenade, and $14 B Cash |
| 11 | Bandito Bobritto and Firework Bazooka |
| 16 | Bombini Gussini and Deadlift Drop |
| 25 | Gymbroini Sigmalini, Pickup Pot, and Buff Spinaccio Seed |
Exclusive items like Gymbroini Sigmalini and Buff Spinaccio Seed are only available during this event.
Can you reset the event and earn rewards again?
Yes, after finishing all 25 milestones, you can reset the event for 10,000,000 Cash. This lets you replay the event and earn rewards again, including duplicates of exclusive items.
How to find the right Brainrots fast
To save time and avoid frustration:
- Use the inventory search to find Brainrots within the needed weight range.
- Keep track of your Brainrots’ weights when you catch or hatch them.
- Submit the lightest Brainrots that still meet the range to save heavier ones for later.
- During the event, Brainrots and plants have a higher chance of getting the Amped Up mutation, which helps your progress.
This strategy helps you move through milestones smoothly without wasting your best Brainrots too early.
The Gym Gains event adds a fun twist to Plants Vs Brainrots by mixing strategy with collection. Unlock Central Island, start submitting Brainrots by weight, and enjoy the exclusive rewards. When you finish, resetting the event is a great way to get even more rare items.
