>>5174190>Toyhammer QuestThat is almost literally what happened in that one Donald Duck comic where he got obsessed about beating his nephews at Kwarhammer. He bought hundreds of units and stole radioactive waste from behind the gameshop, thinking it was paint. At night the wind opened the window in his basement, knocked the cointainer over and the fumes made all of his figures come to life and try to take over the city.
The tripplets stopped/killed them all by stealing the Stone of Black Magic and throwing it into the paper shredder, because lore said that the warriors wouldn't stop fighting until it was destroyed.It wasn't 40k, though.
