Your whole series is cute as hell, truly adorable. However. I think something much darker and sadder is happening here. Adeleine is a very sad person, somehow alone through no fault of her own. Ostracized by the community at large and unable to have any friends she has resorted to making her own. Each "kirby" is in fact a wad of used gum. Each is a different colored wad and her broken mind interprets this as eye color. She makes up stories about their personalities and adventures. In reality she is just a very lonely girl, playing with ABC gum wads she finds in the park. If mini kirbys where real, everyone would want them, or even steal them. But no, nobody will steal her gum friends. They just keep walking, pretending they didn't see a heart broken soul crying out for affection.
