The Pillar is a giant thing that randomly spawns in the city for absolutely no reason. The Kirbys have to bust it for no apparent reason. It contains sexy patches.
The Pillar is well known for spawning in Random Places, especially on top of buildings and in the middle of busy highways.
One time while Poyo Ride was playing air ride, the pillar spawned in. Nothing unusual. However, after busting the pillar, there was the usual patches, but there was a star in there! Unfortunately, it was not the Shadow Star, but the Wheelie Scooter. Poyo Ride believes that the pillar spawned on top of the scooter, or the scooter spawned inside the Pillar.
