Yellow Core

The Yellow Core is described here as an exclusive Rare crop, and that "exclusive" tag is the real story for its economics. Exclusive crops are not sold in the standard rotating shop, so unlike a normal Rare seed you cannot simply rebuy it — once your stock is gone, it is gone, which quietly raises its practical value above its modest Rare label. With no recorded seed cost, sell price or growth time in this entry, you should treat it as a collector and synergy piece rather than a calculable profit engine.

Mechanically, the Yellow Core is a Fruit type crop, so it benefits from any Fruit-targeted pets, sprinklers and event items you run. Fruit is a broad, well-supported category, meaning your existing Fruit-boost infrastructure carries straight over to it with no extra setup.

For mutations, a Rare base value is fairly low, so flat additive mutations barely move the needle — your only path to a high payout is stacking strong multiplicative mutations to amplify that small base. Realistically, grow Yellow Core when you want to preserve a limited exclusive or feed a Fruit-type collection, not as a core income crop; its rarity scarcity matters far more than its raw sell figure.
