Not Mushroom for Error Fable walkthrough in The Sims 4

To complete the Not Mushroom for Error Fable for Spruce Almighty, you need to solve all Mushroom riddles. There are four colored Mushrooms sitting fairly close to his tree, and you must interact and satisfy the conditions presented by each one to finish this quest.
Mushroom | Riddle | Solution |
---|---|---|
Blue Mushroom | “Enchanted not, a natural glow. In day I sleep, at night I show. An eerie hue of ghostly play, instead of fright, I light the way! What am I?” | Bioluminescent Mushroom – Lightning Root Leaves |
Red Mushroom | “I’m often red, with spots about. I’m seen in film to gain some clout! I’m a fungi, I swear it’s true, but if you touch, Grim collects you! What am I?” | Amanita Muscaria |
Green Mushroom | “A Laurent chef’s awarded dish. A forager’s ultimate wish. Rich but not rare, the Landgraab’s eat, but to the rags, a chocolate sweet. What am I?” | Truffle – 5,000 Simoleons |
Yellow Mushroom | “Come dance about, it’s time to play. Good luck or bad, we’re here to stay. A portal to a fairy land? Or toadstool spores’ outward expand? What am I?” | A Fairy Ring – Be a Fairy or unlock an Enchanted by Nature journal entry |
All riddle Mushroom locations in The Sims 4
Before you can get to work solving the Mushroom riddles, you need to know where to find each one. All four of them are fairly close to Spruce Almighty’s tree in the Sprucederry Grove region of Innisgreen, but they blend in with the environment quite well and can be easy to overlook. Here’s where to find each one.
- The Blue Mushroom can be found near some green bushes and purple flowers, just a few steps away from Spruce Almighty’s tree. It’s also fairly close to a small stone wall.
- The Red Mushroom can be found right on the other side of the path leading up to Spruce Almighty’s tree, decently close to the lamppost and bush right by it.
- The Green Mushroom can be found near the Red Mushroom, a bit further away from the path.
- The Yellow Mushroom can be found near the corner of the green area, close to Spruce Almighty’s tree, behind some green bushes and a stone fence.

Solve Blue Mushroom’s riddle in The Sims 4
The correct answer for the Blue Mushroom’s riddle is Bioluminescent Mushroom, but you can’t select this option unless you have Lightning Root Leaves in your inventory. To acquire this special item, you either need to plant and grow a Lightning Root plant yourself or find one you can pick from out in the world.
If you want to get this quest done as quickly as possible, it’s best to find one in the wild. You can find a Lightning Root plant over in the Fairy neighborhood Everdew in a circular patch of grass close to the Summerdream family’s home. Once you collect leaves from this plant, head back to the Blue Mushroom and select the Bioluminescent Mushroom solution to finish this riddle.
Solve Red Mushroom’s riddle in The Sims 4
The solution to the Red Mushroom’s riddle is Amanita Muscaria. You’re only given two options to choose from for this riddle, which are Amanita Muscaria and Fly Agaric, so it’s a bit of an easier one to get done.

Solve Green Mushroom’s riddle in The Sims 4
The answer to the Green Mushroom’s riddle is a Truffle, but you must have at least 5,000 Simoleons in your household to choose it. The other option you’re given, which is a Mushroom Steak, won’t complete the puzzle, so if you don’t have enough, get to work earning until you do.
Solve Yellow Mushroom’s riddle in The Sims 4
The correct answer to the Yellow Mushroom’s riddle is a Fairy Ring, but you can only select this answer if you are either a Fairy or have unlocked an Enchanted by Nature notebook entry. This means you either need to work on becoming a Fairy or find something unique to this expansion pack world.
If you’re not interested in becoming a member of this occult, the easiest way to unlock an entry is through foraging. There’s a decent chance you already have one at this point, so you may not even need to go searching. If you do, though, foraging around is the best way to unlock an entry. Once you’ve done one of the two requirements, return to the Yellow Mushroom and select a Fairy Ring to officially finish this Fable. Completing this quest gets you a Glasswood Tree and some Everdew Seeds.
