Probable, but I never heard mention of it before. I never really cared, Octoroks were my least favorite enemy at the time OoT was out. Spitting rocks at you = not cool. At least on my standards, it isn't cool.What I mean is that they were ashamed of not having an octorok in TP, so they decided to make a backup when ST came out.
@HoT:
By they way, octoroks in OoT, MM, and TWW.
