What are Sparkling Cube odds for each egg type?

The egg you put the cube on matters more than the cube when you want a rare style. On an ordinary egg, Shadow cannot happen at all, and almost every hatch comes out in the common Sparkling style. Egg Heist eggs have their own odds, and Dazzling is the one style they can never give you.

Shadow is a sparkling variant that looks clearly different from the other sparkling hues. If that look is what you want, hatching ordinary eggs with cubes will never get it. Dazzling works the same way in reverse: don't spend a cube on an Egg Heist egg hoping for it.

The Sparkling Cube is bought with real money, so check the egg before you use one. Whatever style you get stays when the Aniimo evolves. If any Sparkling will do, you don't need a cube. Applying Sparkling Marks to an Aniimo you already own turns it Sparkling for 10 sparklings.

Not settled: The Egg Heist chances for the common and Shadow styles are not settled, and neither is the Dazzling chance on an ordinary egg. It is also not settled whether a cube-hatched Aniimo always gets perfect potential.
