The Dinosaur King, ruler of Dinotown, once contacted their ghostly neighbours and convinced them to create a staircase that would allow the Ghost World inhabitants to invade Skyrock Mountains and rule the world of the living. To ensure the staircase would float up that high, the sisters created a Power Jar that would make the stairs invulnerable as long as the artifact was not destroyed. After learning of their involvement, Shion decided he would pay a visit to Witchery World and deal with the women. However, this adventure never happened in Sonic the Comic.
