The next Plants vs Brainrots update is focused on the huge bosses. Players will fight new bosses and earn exclusive rewards from them. These aren't your typical brainrots – bosses feature significantly increased health pools, unique attack patterns, and devastating abilities that can overwhelm unprepared gardens.
Boss Battle Features:
One of the latest sneak peeks from the developers is the Rainbow event. As per the leaks, during the event, players will gain improved luck and mutations. The Rainbow event transforms the entire game atmosphere, creating opportunities for acquiring the rarest mutations in the game.
Rainbow Event Benefits:
One of the highlights of the new brainrots will be the 67 brainrot. This will be one of the limited brainrots, which means holding onto one is a must for the brainrot collectors. Limited brainrots like the 67 are exclusive to specific updates and never return once the event ends.
67 Brainrot Characteristics:
Success in the Bosses update requires careful preparation. Make sure you have your plants ready to handle the massive creatures coming your way. Here's my proven strategy for maximizing your chances:
Based on extensive testing, here's the optimal defensive setup:
Front Line (Rows 1-2):
Mid Line (Rows 3-4):
Back Line (Rows 5-6):
Join Plants vs Brainrot one hour early and avoid missing out on the iconic admin events and the mutations you get from participating. Admin events typically begin 30-60 minutes before the official update time, offering exclusive opportunities for early adopters.
After analyzing community strategies and testing various combinations, here are the top plant choices for the Bosses update:
| Plant Tier | Recommended Plants | Base Damage | Mutation Priority |
|---|---|---|---|
| Secret | Mr. Carrot | 3,500 | Neon > Diamond |
| Secret | Tomatrio | 8,750 | Neon > Diamond |
| Godly | Carnivorous | 2,000 | Diamond > Neon |
| Mythic | Watermelon | 750 | Diamond > Frozen |
| Legendary | Eggplant | 300 | Frozen > Gold |
Mutations are crucial for boss battles. Here's the damage multiplier breakdown:
| Mutation Type | Damage Multiplier | Special Effect |
|---|---|---|
| Neon | 5x | Glowing aura |
| Diamond | 5x | Crystal appearance |
| Frozen | 4x | 0.3s freeze on hit |
| Gold | 4x | Golden shine |
| Normal | 1x | Standard appearance |
Pro Tip: A Diamond Eggplant (1,500 damage) outperforms a Normal Watermelon (750 damage), proving that mutations often matter more than base rarity.
Boost your boss-fighting capabilities with these active codes:
| Code | Reward | Status |

| BASED | $5,000 Cash | ✅ Working |
| STACKS | Lucky Potion | ✅ Working |
| frozen | Frost Grenade | ✅ Working |
Codes typically expire within 2-4 weeks, so redeem them immediately to avoid missing out on free resources that could make the difference in boss battles.
With bosses now being a major part of tower defense in the game, things are about to get hard. Unlike regular brainrots that follow predictable patterns, bosses introduce dynamic challenges:

The 67 brainrot is one of the limited brainrots, which means holding onto one is a must for the brainrot collectors. Limited brainrots never return after their event ends, making them valuable for trading and collection purposes. They also typically offer superior income generation rates.
With bosses now being a major part of tower defense in the game, things are about to get hard. Bosses require coordinated defenses with multiple high-tier plants. Players report needing at least 10 million in resources and several Legendary or Mythic plants to consistently defeat them.
While you can join the Rainbow event immediately, joining Plants vs Brainrot one hour early gives you the best chance at rare mutations. Without proper preparation (cash reserves and strong plants), you'll miss most event benefits.
Boss-exclusive rewards like special mutations and the 67 brainrot are only available during the event period. Once the next update launches (typically the following Saturday), these items become unobtainable, though you keep any you've already acquired.
New players should focus on:
Plants vs Brainrots drops its major updates every weekend, especially on Saturday. Minor patches and hotfixes may deploy throughout the week, but major content updates follow this consistent schedule.
You can also expect the latest Plants vs Brainrots codes with the new event. Historically, each major update includes 1-3 new codes offering cash, items, or exclusive rewards. Check the official Discord immediately after update launch.
While bosses are designed to be challenging solo content, having optimized plant setups with proper mutations makes solo victories possible. The community recommends at least 15 plants with Gold mutations or higher for consistent solo success.
All your existing plants and brainrots remain unchanged after the update. The new content adds to the existing game without removing or modifying your current collection. However, the meta may shift based on boss requirements.
The Plants vs Brainrots Bosses update represents the most significant content addition since the game's launch.
