As Spectrobes in the Kaio are unable to evolve by themselves like in the first and second games, the player must feed a Spectrobe the Evolve Mineral to initiate evolution. One criteria must be fulfilled in all cases, however; Child and Adult Spectrobes must be at Level 5 and 30, respectively, or of a higher value for evolution to take place. If a Child Spectrobe uncovers an Evolve Mineral while searching in a field, it gains 64 EXP.
