Here's the problem: Hypotheliciously has been shrunken by the poison mushroom, making him even smaller and lighter than even I am, giving him two votes already. If there were to be no votes for him, this makes it much easier for someone to swoop in and vote him out, especially the Mafia who can work together. Plus, there's always that small possibility that he's Mafia and has been trying to hand his item off to a cohort, though that seems unlikely now.
I don't trust anyone as much as I do myself. Whether it's me or not, a townie will be hit tonight. If the Smash Ball dies with me then at least some other townie will live. Besides, I'm Pichu, it's kind of my thing to self-destruct.
