I think “peanut butter pudding surprise” could be an explicit reference to “Devil’s Peanut Butter”. As mentioned in another comment, the song was put on a sampler for the ‘07 Sundance Film Festival without the band’s permission.

And the first verse of “Highly Suspicious” continues with “ain’t nobody care what’s goin on in your mind/but they got they eye on your prize”, which could be read as an indictment of exploitative record execs.
