The targets of the mission "Splinter Group" are four mutated raiders named Mick, Lee, Ralph, and Dan. This is a play off of the Teenage Mutant Ninja Turtles named Michelangelo, Leonardo, Raphael, and Donatello. The other similarities include their hideout being in the sewers, their name "Splinter Group" after the rat master "Splinter", their surfer-like language ("dude", "brah") and their craving for pizza used to lure them out.
