Minecraft wiki entry for Snowy_Plains, associated text: Pillager outposts and Igloos are also found. Igloos are difficult to spot in the plains, due to the snow blocks camouflaging among the snow layers. Villages that generate in snowy plains are made of spruce wood, snow blocks, ice, blue ice and packed ice. Polar bears and strays spawn here, the latter a variant of the skeleton that shoot arrows of Slowness.
