For

Cherubi having adapted to areas with much more berry-eating pokemon. It has a much more grouchy, combative disposition and on top of punching and whipping using the vine growing from its head, the berries it yields taste incredibly sour. Despite this, the juice from their berries makes an excellent drink if diluted just right.

This variety of Cherrim normally act aloof and dignified, but if exposed to strong sunlight, they reveal their true form. Their sunshine form is always up to a challenge and fiercely attacks foes with powerful punches despite its small size.
