Sparkle Bloomies are super rare Bloomies with a different color. They are always either rank S or S+ (a 50/50 chance) and are worth 5× more gold when sold.
The base chance is tiny, but you can raise it with the Sparkle Chance skill and later with the endgame skill Guardian of the Sparkles.
Hats from S+ Bloomies
The first time you hatch an S+ Bloomie of a kind, it drops a one-time gift: its very own hat! Sparkle Bloomies have their own sparkle version of the hat, so you can collect both. Hats can be put on your Bloomies, and you can adjust their position and size in the Bloomie Box.
More hats are available in the shop.
