When a Pink Horror is slain in close combat (not removed as a result of Daemonic Instability). Roll a D6; on the result of 1-3, the Pink Horror will explode, inflicting an automatic S 3 on the unit that inflicted the Wound, distributed as a missile attack. On the roll of a 4-6, the Pink Horror will split into two Blue Horrors instead; replace the slain Pink Horror with two Blue Horror models at the back of the unit. If you do not have access to enough Blue Horrors, treat the result as having rolled a 1-3 instead. When resolving attacks against a unit with both Pink and Blue Horrors present, the Blue Horrors are targeted and removed as casualties first.
