Wow, reading that brought back memories of scouring the web for ZT cheats and tricks in the early 2000s.
Back then it really was plenty reasonable to believe just about anything you'd read, since a lot of ZT's real working cheats were so genuinely strange. The devs had a LOT of fun with easter eggs.
But yeah, those were fake. So was the "dragon" that you were supposed to get by putting a bigfoot, a penguin, and a crocodile in an exhibit together, and a lot of others.
So many of the real easter eggs seem so unlikely that back before folks had gone through the game files with a fine-toothed comb, you really never knew what you'd get.
The yellow-brick road one sounds SO fake but sure enough, it's in there.
I still don't get a lot of what I assume are meant to be joke references in some of the cheats. What's the deal with a Grizzly Bear named Deer that climbs fences? That's got to be something, right? Deer don't climb fences. Was I not privy to some national news story in 1999-2000? I've always been so curious about some of these.
