Every pair for Neptilius

• Faleris Aqua

No gender rule applies here: any male and female of the parent species work, in either order. The cake does not change the species. It changes the eggs: a Vegetable Cake lays 2 eggs per breeding, an Extravagant Vegetable Cake raises the mutation chance from 1% to 3%, and a Special Cake makes inheriting several passives (up to 4) much more likely. See the mutation calculator and the passive odds tool.
