A viral internet campaign that was started in July 2025 in response to a tweet by user @TaruTaru_Mage encouraging people to donate fresh ryegrass to the retired racehorse Haru Urara (Racehorse). Owing to both Haru Urara's historic popularity and the popularity of her Umamusume counterpart, Urara's farm received a ridiculous amount of donations amounting to multiple metric tons worth of ryegrass (though thankfully, the donations being monetary meant the excess funds could be used to benefit the farm in general).
The event spurred a large amount of art featuring the Umamusume Urara being flooded with comical amounts of ryegrass, much to the confusion of her friends and Trainer (Umamusume).
