Paranormal portal

A Paranormal Portal is a purple-ish color portal that, when activated by King Boo, releases the strong version of all the main ghosts in Evershade Valley to join his army. If Luigi does not capture all of these ghosts in time, the dimension will collapse among itself. The portal leads to an illusion which is the home of the Tough Possessor. The portal itself is located in the Terrace in both missions, A-5 Paranormal Chaos and Stop the Knightmare.
