Crane attempts to evolve his pet, Bubble, which the Federation previously believed had no evolution path. Surprisingly, the pet surges with strong evolution energy, raising hopes it might rival Xavion's powerful Flame Gryphon. However, others doubt such a low-rank pet could achieve more than a minor upgrade. As the evolution completes, Bubble’s new form appears only slightly changed, disappointing the onlookers. The episode ends with the realization that Bubble’s evolution has likely failed, confirming the Federation's earlier assessment and leaving Crane’s breakthrough in doubt.
