After VIDDA and the Vantablack children took the color potions to the Pastel witches, they managed to produce one pot of antidote for the zombies. Fortunately it was enough for the entire island and there was still left over. They gave the rest to VIDDA, as a gift, in case it needed to help other islands. VIDDA keeps this potion with it to this day, as a memento of the day it was able to help the children of Pastel reconnect with their parents.
