"Plok!" continues the Follin brothers' incorporation of old rock music influences; "Beach," for instance, was inspired by the works of Steve Wonder, its guitar solo influenced by Queen guitarist Brian May. Tim Follin composed the title song out of a guitar-played two-chord progression of "Tequila" by rock and roll group The Champs, as two guitar chord samples could fit within memory. "Lead" instruments such as an electric guitar and harmonicas were made out of simple waveforms, with the guitar's wave identical to a square. A breathing sample in the boss theme was also used in "Equinox" and "Spider-Man and the X-Men in Arcade's Revenge" (1992).
