Hidden Palace Zone
Act 2 is just like act 1, but it starts you off in the wall and no rings, items, badnicks, or the emerald are to be seen in act 2. There are two kinds of badnicks here: A little T-Rex robot and a big Bat-like robot. The music is the same as 2 player at Mystic Cave. This was the only secret level to make it into the final version, but it is hard to get to and it is messed up. It would have appeared between Mystic Cave Zone and Oil Ocean Zone. Below are 4 screenshots of Hidden Palace Zone from the Alpha version. There are triceratops badnicks and if you look closely, the ground, background, and level layout is different.
