Volt Goat

The Volt Goat is an animal found in the Reign of Giants DLC and is indigenous to the Desert biome. It is essentially a living Lightning Rod; any lightning strikes in the vicinity will seek out and supercharge the Volt Goat, causing it to appear to radiate electricity and glow.

Normally a docile creature, a supercharged Volt Goat becomes highly aggressive. While supercharged, any attacks made by a Volt Goat or any attacks made on a Volt Goat will damage and stun its opponent with an electric shock.

Upon death, a Volt Goat will drop 3 Meat and has a 33% chance to also drop a Volt Goat Horn.

Similar to Beefalo and Rock Lobsters, Volt Goats roam and reproduce in herds. Unlike Beefalo, attacking one Volt Goat will not cause the rest of the herd to become hostile to the attacker.

Trivia
but the idea was later scrapped.
 * Volt Goats were planned to be exclusive to their own biome filled with Tesla Trees
