Ok, I did a little reading, and the fact we have a cultist role means that in order for the town to win, we must be even or outnumber the cultists AND the mafia. So things are more dire now than it seems, so we need to control these two groups asap. So with the little research I did on Epic Mafia roles, I am prepared to make a vote.

My reasoning is NOT because he's a bad cream, but because he's possibly a Froyo. A Cultist visits a person every night and converts them to being a Cult. Who do we know made a visit during the night besides the one carrying out the night kill? Whoever encountered the Strawberry, which we're calling the role a Loudmouth. This line of thought also makes me think our Strawberry flavor also became a Froyo, so if my logic is correct here, the Strawberry flavor will also cease to be in our machines...
...We have to make a vote anyway, so I will follow my gut feeling here.
EDIT: Following this logic, and if I understood the Loudmouth role correctly, it was possibly the Vanilla bad cream that carried out melting the Rainbow flavor.
