I've actually seen an idle pikmin holding a spicy berry before. It was in Twilight River. It was on the log at the end of the smaller split of the stream. I think it didn't jump off the lilypad in time. There must of been a glitch, keeping it from jumping of the lilypad. Anyway, there's a lot of glitches involving spicy berries. I'll bet they take a lot of programming, considering how they work.
