The only known full example of the Woolly Creeper that existed back in the last ice age of Minecraft's overworld.
This prehistoric being, excavated from a blue iceberg, is the hairy ancestor of today's modern creepers.
It has been theorized that its longer legs were used for trudging through the heavy snow blocks of the overworld's past.
While the creeper has survived the transition between the ice age and the modern world, it has since
evolved to no longer need its shaggy fur to survive the environments, the warmth of the sun and lack of thick layers of ice covering most the overworld enough to warm its green skin.
Villager scientists have determined that the Woolly Creeper still had green skin beneath the long fur.
Its tusks were developed as a defense mechanism because scientists do not believe the Woolly Creeper had its ability to explode yet.

This example is shown with packed ice arms because it comes out of the ice, and I couldn't think of what to put as creeper arms because creepers don't have arms. :P
