The Welkin Wonderland is the first world of Runner 2: Future Legend of Rhythm Alien. The world is based around the sky, and features anthropomorphic hills bearing sly grins and monocles. Factories and warehouses can also be seen, especially that of the Burger Mouth burger company, which was also featured in the final world of the first Bit.Trip Runner. The boss of The Welkin Wonderland is the Stratosfear, a plane with twin cannons that pursues the runner from behind.
