Violet Cress - Marks down the racers who are the most likely to take places 1 and 2.
Lobelia - Puts a whip mark on the racers that will be in the lower places (possibly the two last places).
Nazuna - At least two out of the three racers she marks will be in the top 3.
RESULTS: x20, x50, x10, x100, x30
It seems Nazuna's third mark doesn't necessarily mean that racer will be outside the top 3.
Additionally, so far Lobelia has always marked the last two racers.
