When harvested, each Potato plant gives 1 potato, with a random chance to produce extra potatoes, partially based on Daily [[Luck]].<ref name="extraluck" />
<ref name="extraluck">The game generates a random number between 0 and 1, and if it is less than 0.2, then another Potato will spawn. This repeats until the random number is greater than or equal to 0.2, at which point the chance for an extra Potato ends. This, on average, will give 0.25 extra Potatoes.</ref>
