That's how it was with me, heh.
What was interesting is when the movie came out in 2000, and there was that set of beanie babies released as merchandise, the Boris beanie had red eyes as well, and then in The Rocky and Bullwinkle Book, there's some illustrations throughout the book where Boris has pink eyes (and Rocky wears a cape for some reason).
Season One was good, I thought, the animation and the designs were iffy, but then again, it took those animators down in Mexico a while to get everything right, Bill Scott once said they could never rely on the Mexican animators to produce anything of "quality", and cites the many different errors like Bullwinkle's color changing from cel to cel and such. Actually, I think just about all the seasons were good in their own way, mainly because when you think about it, there never was any actual character development on the show: no matter what happened, the story always started with things hunky-dory in Frostbite Falls, some unsual predicament happens that Rocky and Bullwinkle investigate because of their obligatory heroic nature, it turns out Boris and Natasha are behind the plot and once they realize Rocky and Bllwinkle try to save the day, they try to destroy them, then Rocky and Bullwinkle save the day while Boris and Natasha get their just deserts. In fact, I guess that's why the "Mucho Loma" and "Ruby Yacht" story arcs are among my favorites, mainly because those are really the only ones that mixed things up a bit by NOT having Boris and Natasha as the main antagonists of the plot, and we find Rocky and Bullwinkle actually end up being victims of circumstance rather than becoming victims of throwing themselves into the fire to put it out.
