When a model with this special rule is slain in close combat (not removed as a result of Daemonic Instability), place two counters next to its unit. After all attacks have been made, but before the combat result is calculated, choose one enemy unit in base contact with this unit and roll a number of D6 equal to the number of counters (even if the Pink Horror unit was wiped out). For each roll of a 4+, the nominated unit suffers a Strength 2 hit (distributed as for shooting). Any unsaved Wounds count towards combat results. The counters are then removed.
