Slogs seem always to be aggressive when they emerge from their kennels. I can’t think of a convincing explanation, right now (maybe they are extremely grouchy when they’ve just been woken up
), but in itself that explains why they attack Sligs at that time.
Slogs emerging from kennels will attack Phleg and not the Slig by his side. In programming terms, I expect this is because they attack whatever individual Abe is possessing, but maybe they simply prefer Glukkon meat to Slig. After all they’re trained by Sligs, not Gluks.
p.s. That Slog glitch is really cute.
It reminds me of the Mulletokons, who kept Slogs.
