What does Gros Michel do in Balatro?

Gros Michel is a Common joker giving +15 Mult. It has a 1 in 6 chance to be destroyed at the end of each round. Once destroyed, your save is flagged extinct, Gros Michel never appears again, and the stronger Cavendish replaces it.

How do you unlock Cavendish?

You cannot unlock it directly. Let your Gros Michel be destroyed by its 1 in 6 end-of-round roll. That flips the gros_michel_extinct save flag and Cavendish enters the shop pool.

Is Gros Michel or Cavendish better?

Cavendish, clearly. Gros Michel gives +15 Mult (additive) while Cavendish gives X3 Mult (multiplicative), which scales far better. Cavendish also breaks far less often, 1 in 1000 versus 1 in 6.

Can I force Gros Michel to go extinct?

Yes. Buy it early and stretch a low-stakes run long so the 1 in 6 roll fires more often. Expected wait is about 6 rounds. Do not sell it manually, since selling does not count.

Can I get Gros Michel back after extinction?

No. Extinction is a permanent save flag. Only Unlock All or deleting the save brings it back, and you will not miss it since Cavendish is stronger.

Balatro Gros Michel & Cavendish

Gros Michel: +15 Mult, 1 in 6 destroy chance. It must go extinct before Cavendish appears.

Gros Michel is a Common joker giving +15 Mult, with a 1 in 6 chance to be destroyed at the end of each round. When it breaks, your save is flagged extinct: Gros Michel never returns, and the upgrade Cavendish (X3 Mult) takes its place in the shop. It is the only joker in Balatro you have to lose to upgrade, and the names come straight from real banana history.

Gros Michel vs Cavendish

Field	Gros Michel	Cavendish
Rarity / Cost	Common / $5	Common / $4
Effect	+15 Mult	X3 Mult
Destroy chance	1 in 6 per round	1 in 1000 per round
Appears when	not extinct yet	after Gros Michel is destroyed

The two never share a shop. A single save flag toggles between them.

How the swap works

Default: Gros Michel is in the pool, Cavendish cannot appear.
Extinction: Gros Michel must be in your Joker slots when the end-of-round 1-in-6 roll hits. Selling it does not count; a Boss Blind that destroys a joker does.
After: the flag flips permanently. Gros Michel is gone for good, Cavendish joins the Common pool, across all future runs.

Why Cavendish is worth it

Cavendish: X3 Mult, 1 in 1000 destroy chance. It only appears after Gros Michel goes extinct.

Chips 200, base Mult 10	Gros Michel	Cavendish
Mult after joker	10 + 15 = 25	10 x 3 = 30
Final score	5,000	6,000

The gap widens as your Mult climbs, and again when Blueprint or Brainstorm copies the X3.

How to force extinction

Hold it across rounds. Buy Gros Michel early and keep it; a full run usually breaks it.
Stretch rounds out. White Stake plus the Blue Deck means more hands per round, so more destroy rolls.
Use a throwaway run. Play one run you do not care about and let the roll resolve without risking a real build.

Buy or skip?

Your state	Call
Not extinct yet	Buy and keep. The 1-in-6 loss is the unlock cost.
Ante 1-3, tight money	Buy. $5 for +15 Mult is top-tier common value.
Deep in a run you cannot lose	Skip. A 1-in-6 destroy can wreck the build.
Cavendish in shop	Buy. X3 Mult is the best common effect.

The banana history behind the names

From the 1820s to the 1950s, Gros Michel was the dominant commercial banana, over 95% of global exports. Then Panama disease (Fusarium strain TR1) wiped out the plantations, since Gros Michel had no resistance.

Growers switched to Cavendish, which was immune to TR1. It is the banana in nearly every supermarket today, and it is now threatened by a newer strain, TR4. The joker's 1-in-1000 destroy chance is a nod to that ongoing risk. The mechanic where Gros Michel must go extinct before Cavendish appears is a retelling of how the banana trade actually changed hands.

FAQ

Can I sell Gros Michel during the grind?

You can, but selling never counts toward extinction. Only the end-of-round 1-in-6 destroy roll sets the flag.

Does extinction happen in a Challenge run?

No. Challenge runs do not advance unlocks. Play a standard run.

Why does Gros Michel feel better early?

At low Mult, +15 additive can out-score a X3 multiplier in absolute terms. Once your Mult passes 100, the multiplier pulls ahead for good.
