Why could Abe not possess Scrabs, Paramites or Glukkons in Abes Oddysee or Slogs before Munchs Oddysee?
Abe may always have been able to possess Glukkons, just not have the opportunity before Abe’s Exoddus. He may also have acquired the ability to possess Scrabs and Paramites when he acquired the corresponding hand scars. Abe’s abilities are constantly growing and progressing. Normally, he can only possess creatures of a certain level of intellect, but by the time of Munch’s Oddysee he has obviously become able to lower himself to the level of Slogs.
