A baby critter crunchie has only one head and can either be pure white or cream white. Critter crunchies get their very first markings through the food they eat. The food turns their heart into rock candy. their candy hearts are covered by fur crests in form of their heart shapes. There runs normal blood in their veins, no milkshake nor an other sweet liquid.
The critter crunchies in this species wip already received their first food, which let them grow bigger, change their hearts into rock candy and gave them their first markings. if they feed on bigger food animals the more bigger and the more heads they grow. they will be able to grow another head. Critter crunchies can grow maximal three heads.
