Card Communes are the forms Mepple and Mipple take on to disguise themselves while at the Garden of Light. The forms bear a vague resemblance to an average looking cellphone or a makeup compact with pink coloring and five small blue buttons. They look identical, except with Mepple's pieces being pink and Mipple's being blue.
The form also helps Nagisa Misumi and Honoka Yukishiro to transform into Pretty Cure when the need arises. When Nagisa and Honoka are transformed, the Communes are kept at their hips in small purse-like pouches.
