It's all possible. But I think that Wood Zone being remade into Mushroom Hill Zone doesn't seem that possible - I don't know why, but I don't.
Well, if you can count the multi-thousand bushes in there, the mini-boss chopping wood and the zone boss trying to dodge trees, I think that's a possibility.
I haven't ventured some guesses, so here I go: Sandbox of Doom Zone Death Trap Zone Sandy Zone That Zone With Alot of Sand That Sonic Needs to Get Through <-- I like this one the most.
Those things were mostly random, since getting level select in S3 without an S2 cart is next to impossible...
Dusty Caves Zone Sandy Hill Zone Yellow Canyon Zone Quicksand Fever Zone And for the winter zone... Crystal Snow Zone Winter Wonderland Zone Snow Desert Zone Glaicer Panic Zone
Here's a few ideas: Desert or ice level Dust Canyon desert levels Dry Oasis Heatwave Horror Ice levels Frosty Desert Frostbite (zone)
Haha, nice one. Sun Tempest zone Yellow of the Egg zone Endless Beach zone Hot Tea zone Absolute Zero zone Tall Tall Mountain zone Ice Tea zone ( :lol: )
Wild West Zone Neo Desert Zone Hidden Desert Zone Outback Desert Zone Desert Strom Zone Death Valley Zone Just to name a few ideas.
But "It was designed to have a palette change" sounds SO much like it was part of one level! The fact is HAS a palette change, rather than her changing the palette, which would be the case if it was a separate zone.
