A painted goblin is a goblin painted white. Players on the guards side during the 2014 Goblin Invasion event must paint the goblins white with an event rpg in order to make them attackable. Also while a goblin is painted, guards nearby will attack and kill it. Goblins may de-spawn if there are many goblins around, and it hasn't died. even during combat, and even in the death animation.
