Mystery Goo
Dropped By
  • White Mushroom
  • Rare Truffle
  • Black Fungus
Best Farming Spot
  • Deep Jungle – Camp
Bambi Location
  • N/A

The best way to farm Mystery Goo is by entering the Deep Jungle via the Camp save point, and then entering and exiting the tent until you get a bunch of White Mushrooms to appear.

Once they appear, watch their animations and cast the appropriate spell. You have to do this three times consistently.

If you get all three spells correct, you have a 20% chance of a Mystery Goo dropping. Otherwise, it’s only a 10% chance.

Note: All 3 types of mushroom heartless can drop Mystery Goo, but White Mushrooms are still by far the easiest to farm.


Once you encounter White Mushrooms in any area of a world, you’ll have to leave the world entirely (exit to the Gummi Ship) and return to reset their spawn chance.

Is this a pain? Kinda, but this is the most efficient method to get your goo.

White Mushrooms

As the bread-and-butter of the Mystery Goo game, White Mushrooms are the most reliable and easy source of the material.

Yes, the drop rates aren’t great.

But their little game is easy to play and win.

White Mushrooms will randomly perform certain actions and you cast a specific spell on them depending on which it is. After three correct casts, the Mushroom will shower you with gifts and vanish.

If you get one wrong, it’ll vanish in anger.

If you get three correct with different spells, you have a 10% chance of a Goo. If you can get all three with the same spell, then you have a 20% chance of getting your goo.

Going for the trio is best, but not always possible.

White Mushrooms don’t hang around forever and only give you so many chances before leaving.

Take a look at each of their animations and the corresponding spell to match:

Rare Truffles

Rare Truffles are another breed that can appear in either Monstro’s Throat, Halloween Town’s Bridge or on the Deck in Neverland.

These blue guys want one thing when they show up: they want to fly.

How can you help them?

By hitting them into the air and keeping them there.

You get rewarded for how many times you juggle them before they hit the ground, with the odds of a Mystery Goo going up at certain intervals:

Juggles Reward Odds
10-49
  • Mystery Goo (20%)
50-99
  • Elixir (100%)
  • Mystery Goo (40%)
  • Shiitake Rank (100%)
100
  • Megalixir (100%)
  • Mystery Goo (100%)
  • Matsutake Rank (100%)

The best place to challenge them is in Neverland and for one reason: you can fly.

It is still a tricky task, though.

The 100% rate of a Goo at 100 juggles may seem promising, but it’s a much slower, more skill-based approach.

In Neverland, start flying and once a Truff makes a jump, get to it.

Aero helps because a Truffle hitting the shield counts as a juggle. Also, take off all of Sora’s movement-based keyblade abilities, such as Vortex and Zanzetsuken. You want simple swings that won’t mess up your rhythm.

Finally, try to get the Truffle out over open water. That way you can avoid it accidentally landing on one of the masts.

This whole ordeal has a definite learning curve, but you can do it!

Black Fungus

The third mushroom in the fam is the Black Fungus.

These guys are the most unreliable when it comes to Mystery Goo.

In order to get a drop, you have to defeat them with a critical hit. Doing so will guarantee you a Mystery Goo–however, this is much easier said than done.

Thankfully, you have a few tools to make this easier.

The most helpful is the Wishing Star keyblade. You can find this in Geppetto’s house in Traverse Town. Its unique property is that it always finishes a combo with a critical hit.

Does this mean you’ll always get the killshot? No, but it very much helps.

Something else that can help is removing all Combo Plus abilities, as well as movement-based keyblade attacks, such as Vortex. This helps you keep track of when exactly your last hit will be, and subsequently, determine if you’re going to finish it.

You’ll need 10 Mystery Goo to make one of everything that requires them.

However, this number might increase a bit more depending on how you use your Mythrils and Dark Matters.
