Zodiac Transformation Dice (Japanese: 十二支変身サイコロ Jūnishi Henshin Saikoro) is an episode of the 2005 anime series. It first aired in TV Asahi on December 31, 2017.
Nobita only has a kite with the previous year’s earthly branch word imprinted on it, so he turns to Doraemon to understand the zodiac. He finds the Zodiac Transformation Dice and uses it to surprise Shizuka by turning into a rabbit, only to lose it after he eventually gets kicked out and when she later terrifies her friends by mistake while playing a board game. Later Gian and Suneo take the dice to the annual “Lucky Man Run” and turn it into a "real animal race" when they drop the dice.
Gian and Suneo participate in the “Lucky Man Run”, which dates back to a tradition started in the 14th century when locals hurried to the Nishinomiya shrine in Hyogo Prefecture on New Year’s Eve to offer prayers for prosperity; the race's victor is recognized by priests as the year's "lucky" man or woman.
