Due to the accelerated schedule for the global version of Umamusume: Pretty Derby, the Halloween Trainee alts for Rice Shower and Super Creek are only just joining the worldwide version on November 24, 2025. They are also joined by two new SSR Halloween-themed cards with Tamamo Cross and Zenno Rob Roy on them. That banner and a Halloween Makeover will be live until December 6, 2025, and the new characters and cards will join the general poll after that.
Like many other alts, the Halloween Rice Shower and Super Creek alts aren’t all that different from their standard Trainee versions, in terms of stats, though they have different Growth Rates and skillsets. Chiffon-Wrapped Mummy: Super Creek is still designed to work as a Pace Chaser who focuses on Medium and Long distance Turf races. She comes with the Unique Skill Give Mummy a Hug, which helps her break out of the pack and pass on the final straight if the positioning is right. Other notable Potential Skills include Professor of Curvature and Mystifying Murmur. Vampire Makeover: Rice Shower is intended to be a Pace Chaser who runs Medium and Long Turf races as well. Her Unique Skill Every Rose Has Its Fangs is more conditional, since she needs to be both well-positioned and pressured by another runner for it to restore stamina. Her most remarkable Potential Skills are Tantalizing Trick and Corner Recovery.

In the case of the Halloween SSR Support Cards, you should basically only pull for the Beware Halloween Night: Tamamo Cross Power card and Magical Heroine: Zenno Rob Roy Speed card if you raise a lot of Late Surgers, as both of the major Career Event skills you earn from them are for those types of runners. The Tamamo Cross one’s is 15,000,000 CC, which increases velocity on an uphill for a Late Surger. The Zenno Rob Roy one could give a Late Surger the Lie in Wait stamina recovering skill that works if they’re near the back mid-race.
