This is an idea I've been throwing around for years now, since one of my original times playing through the game. In a few different places, you'll notice that a plain looking cat just...comes in. In Ozzie's Fort in 600 AD, the cat comes in and flicks the switch that sends Ozzie plummeting to his doom. Or to his basement. Either way. Also, I believe that you also see the cat in either the Tyrano Lair or Giant's Claw. Something prehistoric related. I don't remember if the cat pops up anywhere else.
Well, I originally thought that person the cat could be the Entity (this was more jokingly thought, however) or a tool of the Entity. Since it has the same sprite as Crono's cat, I just kind of figured that it was.
Earlier today, while playing, though, another thought popped into my mind: If it is Crono's cat, could it possible be because of the ending in which Crono's cat jumps through a gate? (And then his mom, heh.) From that point, could his cat have wandered around through times, thereby effecting previous events?
Now, does anyone remember which gate Crono's cat jumped through in the ending? It was the last one, correct? Was the last one leading to 600 AD? Since I think it is the Giant's Claw where the cat pops up, that would make sense -- both that and Ozzie's fort are located in 600 AD.
What do you guys think? Plausible or not?
