Loopy Landscapes - Thunder Rocks: This park is a duplicate of Thunder Rock from RCT1, Just with another rock
Wacky Worlds - Great Wall Of China Tourism Enhancement: Despite not being able to make changes to the base landscape, you are able to delete the pre-placed scenery. Thus, you can destroy the eponymous wall and the nearby temple. Not that it helps, because this scenario doesn't have money.
Time Twister - Robin Hood: The objective only requires 3-4 clicks to complete, as you can simply raise the price of Log Train Junior Coaster to 10$ (or respective currency), to achieve high ticket sales.
