The Mix Communes (ミックスコミューン Mikkusu Komyūn?) are the form that Flappy and Choppy take when in the Land of Greenery in Futari wa Pretty Cure Splash Star. Much like Mepple and Mipple of Futari wa Pretty Cure, they come with special diamond cards that provide them with food, health and sleep. They are also used by Hyuuga Saki and Mishou Mai to transform into Pretty Cure by chanting "Dual Spiritual Power!" together.
Like their predecessors, the girls have to be together to make the transformation work.
The Mix Communes resemble cellphones, as they're stated to be "The most common object of the current era in this world". Which means they wouldn't look out of place in this form as many other people have cellphones. They are white with golden colored designs and 3 different hearts on the front and a segment dedicated to the girls' color.
The equivalent of the Card Communes that allow transformation and care of Flappy and Choppy. Diamond Cards (プリキュアダイヤ Purikyua Daiya?) cards are light pink diamond shaped cards with rainbow bar codes along the top. They must be inserted from the top part and then spun in circles.
Unlike the previous series, where they would form bubbles with the mascots inside, they appear in a puff of smoke and are normally half the size of an opened Mix Commune. Also when held back to back, items can be transferred or given to the other commune, as a present.
