Tiny Eden: getting mutated peas to count
Splicing alone does not finish it. The developers' advice is to plant new seeds once you have the quest and harvest those, and players add that spliced genes only take effect after you replant. If you did all of that and the harvest still did not register, Update #5 on 12 September lists a fix for the Harvest Mutated Peas quest.

The step people skip
The quest reads like a harvest task, so players splice their peas and then wait for the plants already in the ground to produce something mutated. Players who tried that report the existing crop did not change, and the developers' answer to a player stuck at this point was about new seeds.
Players who answered describe the same order: splice, replant, then harvest the new plants. One also found a bug that makes this worse, where old seeds show a mutated status but their harvest does not count.
- "Have you replanted them? I noticed my produce didn't update the quality until a new crop was planted. Then I got produce with a green flag."
- "Game bug: old seeds incorrectly show the "mutated" status, but their harvested fruits are invalid and won't count towards quest progress."
Splicing in the Gene Lab
Using the machine has two parts, and one player points out it is easy to do only the first. Adding plants is not the change itself: you pick the plant type and use a plasmid to make it genetically different, and it is not based on the quality of the seed.
How many splices you can make depends on how many plants of that species you have added, according to one player's account. They spliced cold resistance first and heat resistance second, then planted, and their harvested peas came out marked with a blue border for rare.
If the Splice button stays greyed out, see the splice button page.
| Plants of one species added | Splicing option (one player's account) |
|---|---|
| 10 | First option |
| 40 | Second option |
| 100, 300, 600, 1,000 | Further options, unlocked in turn |
When you did everything and it still did not count
Some players followed every step and stayed stuck. One spliced their peas to Uncommon and then straight to Rare, planted and harvested, and the quest did not register; they wondered whether they should have harvested at Uncommon first.
Update #5 lists a fix for this quest, without describing the cause. Update #4 the day before also changed a quest objective to require a rare crop, without naming the quest. If your save is from before either update, update the game and harvest a fresh, replanted crop before assuming you are still stuck.
- Update #4: "Updated a quest objective to require a rare crop."
- Update #5: "Fixed the Harvest Mutated Peas quest."
Peas and beans, chili and bell peppers
A player reading the game in Chinese found the real cause of their confusion was the translation: the words for peas and beans, and for chili peppers and bell peppers, look very similar. Splicing the wrong plant will not advance the quest.
Check the exact plant named in the objective before you splice.
The research side of every harvest that the official FAQ describes is on the breeding page.
The pepper quest works the same way
The chili pepper step has the same shape. One player was stuck on an objective they quoted as 'grow and harvest a mutated chili pepper' despite splicing twice and growing four plants; they later reported the game moved them past it after reopening.
That questline matters beyond the harvest, because players report it is what rewards the Navigational chip needed for the Drone Station project.
The developers' advice on 21 September
A player who had spliced peas could not see any way to take the mutated peas out of the machine, and asked for better descriptions and a tutorial. On 21 September a developer replied that they are working on improving that, and asked the player to try something simpler first: plant regular peas, harvest them, and say whether that completes the quest.
That differs from the route above, which says to splice, replant and harvest the new plants, and the reply does not say what changed. Another player in the thread described the splice route: after splicing, wait for the plant you have to die off, and the next one you plant carries the spliced traits. The player who asked had not answered by the time this was written.
Not confirmed yet
- Whether harvests made before Update #5 count toward the quest is not stated.
- Which quest objective Update #4 changed to require a rare crop is not named.
- Whether the splicing thresholds apply to every species is not documented.
- Whether a harvest of regular peas now completes the quest, as a developer suggested on 21 September, is not confirmed.
Frequently asked
- How do I get mutated peas in Tiny Eden?
- Splice peas in the Gene Lab, then plant new seeds and harvest those. Players report the plants already growing did not become mutated.
- I spliced my peas but the quest will not progress.
- Replant and harvest a new crop. If that still does not count, update the game: Update #5 lists a fix for the Harvest Mutated Peas quest.
- Do old seeds count as mutated?
- One player reports a bug where old seeds show a mutated status but their harvest does not count toward the quest.
