As thunderstorms brew, Mareep wool expands enough to lift their hooves off the ground. Mareep shepards carry them to safety before storm winds send them bouncing across the countryside.

The tail bulb is made of conductive layers suffused with oil, forming a natural capacitor that concentrates its charge into an electric blast. Wool always builds up the same charge polarity, so members of this family will violently repel each other when unloaded from transport.

Without wool, Ampharos instead stores its electricity as a charge differential between the “gems” on its head and tail. It brings them together for its trademark brightness, forming a powerful arc lamp.
