--- By Nik Davila --- Construction of the Parking Spring --- The Theories that I have of Sonic 2 is that Sound #10 Is Hidden Palace.The Dust Hill Zone was Changed to Mystic Cavern.The Colors were probably changed to a nighttime setting. Neo Green Hill Zone had its name changed to Aquatic Ruin Zone. Sonic CD in Level Select had a level missing.2 It could be one of the missing Sonic 1 or Sonic 2 Levels. In Sonic 3 Level Select. You should find a Hidden Palace Zone Picture. In Sonic 1 Sparkling Zone, Parking Zone and Construction Zone was all changed to Spring Yard Zone just as Clock Works Zone was Changed to Scrap Brain Zone. The Missing Sonic 3 Levels were taken out just taken out to get the game on time. Flying Battery Zone was before Ice Cap Zone. It makes sense since in Carnival Night Zone you jump the cannon. And you fall into Ice Cap Zone. After Launch Base was Mushroom Hill and Sandopolis. All the missing zones were added to Sonic and Knuckles. --- Taken from 'Secrets of Sonic the Hedgehog - The Original' http://secretsonic.cjb.net ---
