This is what happens when you pile too much skeep fertilizer onto a more-magical-than-usual bean! The Tangledrift beanstalk lifted up entire chunks of earth as its stem grew to pierce the heavens, creating an ecosystem unto itself high above the clouds. Whatever you do, don't look down.
Some folks have adapted to this ludicrously lofty lifestyle and made the most of their surprise high-rise homes. But even towns in the sky aren't out of harm's reach, and plenty of hazardous creatures make their roost among the Tangledrift's twisting vines.
