What is the rarest Sparkling type?

A Sparkling Cube never gives you Shadow, and it lands on Dazzling only 1% of the time. The other 99% of wild catches with a Cube come out in a common Sparkling style. That is why nearly every Sparkling Aniimo you meet wears one of the standard Types 1 to 10.

Neither rarity makes an Aniimo stronger. Sparkling status is purely cosmetic and adds no stats, so chasing Dazzling or Shadow is a collection goal. It does not upgrade your team. You also cannot pick a colour in advance. Every route to a Sparkling Aniimo rolls its colour for you.

Where Dazzling and Shadow come from

Sparkling Pigment is the repeatable way to chase Dazzling. It rerolls the colour of an Aniimo that is already Sparkling, picks a new colour at random each time you use one, and Dazzling is one of the possible results. It does nothing on an Aniimo that is not Sparkling yet, so you need a Sparkling Aniimo first and Pigment second.

Shadow is harder to plan for. Cubes rule it out completely. Prismatic eggs have a 0.5% chance of hatching with a sparkling or shadow mutation, and that is the one route on this list where Shadow is a possible result. Prismana follow the same pattern as everything else: their ten common colours together turn up 99% of the time, which leaves the rare styles as the small remainder.

Not settled: The number of standard Sparkling variants per species is not settled. It appears as both 10 (Types 1 to 10) and 12, so it is unclear whether Dazzling and Shadow sit outside that count or make up part of it. The game also does not say whether Sparkling Pigment can roll Shadow. Dazzling is the only rare style it is known to produce.
