What kinds of events happen in Plants vs Brainrots?

Here are the main event types you’ll see:

Each event type changes the dynamics of how you farm, fight, and strategize.

Recent & Current Big Events

Bosses Update – Sept 27, 2025

• A major content update rolled out that added multiple new bosses, spawners, and a fresh Rainbow admin event.
• The update also introduced new Brainrots, including the much-hyped “67 Brainrot”.
• The Rainbow admin event boosts chances for rare mutations and gives players more “luck” during the event window.

Code Drops During Events

• During or near big events, devs often drop new redeemable codes.
• Current working codes (as of latest) include:
  • BASED — gives $5,000
  • FROZEN — grants a Frost Grenade
  • STACKS — gives a Lucky Potion
• These codes are not case-sensitive, and can be redeemed once you finish the tutorial.
• While none of the known codes are reported expired yet, they usually don’t last forever, so redeem quickly.

Mutation & Weather Events

• The Frozen weather event appears every 2 hours; during it, plants and Brainrots can spawn with the Frozen mutation, which gives extra power and effects like freeze.
• Mutations like Rainbow, Galaxy, Gold, Diamond, Neon, Underworld, Magma, etc. exist.
  • Rainbow mutation gives ~5× earnings boost for Brainrots.
  • Galaxy mutation gives ~7.5× earnings.
  • Mutations are more likely during admin events or special weather surges.
• Rain, Prismatic, Underworld, Magma and more might be triggered during admin events or as ambient weather changes, affecting mutation chances.

How Boss Events Work — Mechanics & Tips

Boss Spawn Mechanics

• Bosses spawn every 500 normal Brainrot kills (i.e. after 500 wave spawns).
• Which boss you get depends on your Spawner level / Rebirth status. If you don’t meet the level requirement, you’ll see lower-tier bosses instead.
• There are currently five bosses (as of the latest update):
  1. Hotspotini Burrito — default spawn, no rebirth needed
  2. Rhino Toasterino — requires Rebirth 2 / Spawner 2
  3. Esok Sekolah — Rebirth 3 / Spawner 3
  4. Chef Cabracadabra — Rebirth 4 / Spawner 4
  5. Dragon Cannelloni — Rebirth 5 / Spawner 5
• Even if you haven’t unlocked a higher boss, the lower one can still appear (sometimes in mutated/golden versions) until you meet the unlock condition.

HP, Earnings & Rewards

• Bosses have very high HP relative to normal Brainrots.
  • E.g. Hotspotini might have ~15,000–20,000 HP, giving ~$750/s base.
  • Higher bosses scale much higher.
• Some bosses also spawn mutated variants (Golden, Rainbow, etc.) during admin / event windows, which greatly increase rewards.
• Defeating bosses yields not just income but often rare drops, special mutation chances, or exclusive rewards.

Best Practices for Boss Events

1. Prepare your garden ahead of time — upgrade plants, increases lanes, have backups.
2. Use spawn-speed boosts or items to ramp up reaching the 500 mark faster.
3. Fight the boss from spawn if possible (don’t let it walk deep into your field) to maximize damage.
4. Use gear like Frost Grenade to stun or slow bosses, giving your plants more time to damage.
5. Participate right at event start — mutated bosses often spawn early and in greater numbers.
6. Rebirth promptly when you can, so you unlock higher boss tiers for the next events.

People Also Ask / FAQs

When do events usually start in Plants vs Brainrots?

Admin events often begin just before or concurrent with major updates. Weather or ambient mutation events may occur at fixed intervals (e.g. every 2 hours for Frozen). Boss spawns occur after waves of 500 Brainrots.

How do I increase my chances of rare mutations?

• Be active during admin events — mutation rates are bumped during those windows.
• Use boosts (like Lucky Potion) and raise your Luck stat (some from rebirth rewards).
• Plant or capture during weather events (Frozen, Prismatic, Galaxy) that favor certain mutations.

Do I lose my Brainrots when I rebirth?

Yes — your stored Brainrots and cash reset when you rebirth. However, your plants, gear, eggs, etc., remain. Because of this, many players temporarily store their best Brainrots externally (e.g. via alternate accounts or friends) before rebirthing.

Are codes only valid during events?

No — codes can be released anytime, though they often drop near or during events. Some codes are event-only or short-lived, so redeem quickly when new ones appear.

Will new events come in future updates?

Absolutely. The devs have continued introducing new bosses, spawners, mutations, and admin events with each major update (e.g. “Bosses Update”). Expect new event types, rare Brainrots, and new “weather + mutations” combos in future patches.
