The Volt Bunny dashing.

The Lightning Carrot is a pet-summoning item that spawns a Volt Bunny that follows the player. While flying to keep pace with the player, the Volt Bunny dashes and releases a series of spherical blue sparks, which emit a decent amount of light while moving erratically and can spread light over an area. If there are no available tiles for the pet to "sit" on, like when climbing walls or flying, the Volt Bunny will constantly jump around. The Lightning Carrot can be purchased from the Zoologist for 50 GC after completing 50% (270 entries) of the Bestiary.

Trivia

The Volt Bunny is a reference to the iconic Pokémon character and mascot Pikachu, who is colored similarly and whose abilities revolve around electricity. Its animation while flying is also likely a reference to Pikachu's Quick Attack animation from the crossover fighting game series Super Smash Bros., sharing similar erratic movements and particle effects.
The tooltip is a play on the words "ecstatic" and "static", "ecstatic" being a synonym of "delighted" and "static" being an electrical charge.
