Sonic: Yeah, and they used the money to build loop-de-loops on the road. Which, granted, cool as hell for me… but man, morning commutes must be hell for everyone else!
A type of landscape featuring natural formations that are the functional equivalents of theme park rides: Waterfalls, mountain torrents, glaciers or icebergs double as water slides, plot-sensitive erosion has created rock or snow formations that act as rollercoaster tracks or bobsled runs, complete with Ramp Jumps, giant water lilies serve as trampolines or at least provide a fun and bouncy way to cross a stretch of water, hanging vines can be used as ropeways, swings, for bungee-jumping or Tarzan-style transportation and so on...
Alternatively, the setting can be industrial or urban, as long as the environment invites misuse as a carnival ride. This can be both Benevolent Architecture or Malevolent Architecture, depending on your viewpoint and if you liked the "ride" or intended to take it in the first place.
- Perhaps most Egregiously, in Ice Age: The Meltdown there's actually a freestanding ice formation shaped like (and used as) a water slide complete with water mysteriously flowing from its highest point.
- In Disney's Tarzan the winding, moss-covered branches become a sort of jungle skate park for the Ape Man to do some sick moves. (The filmmakers called it "tree-surfing")
- Everybody Edits Flash: The cave is filled with tunnels that push the player's character along in every direction, helped by a large amount of Gravity Screw.
- Rigs of Rods: Typical for many maps, especially those of the proving grounds/test area kind. But then again, they're purpose-built.
- Sonic the Hedgehog:
- Almost any level from the Genesis era titles; particularly the Green Hill Zone with its rolling hills, spirals, and loops.
- On any console, really. Sonic Adventure 2 even has a highway with loops and jumps.
- Speed Highway from Sonic Adventure, which does the same. It makes one wonder how normal, everyday people in the Sonic Universe go about their day-to-day lives, especially when they're trying to get to work...
- Sonic Colors takes this to literal extremes with giant amusement park levels, such as Planet Wisp, which is one in progress.
- Several Wile E. Coyote cartoons feature this type of landscape, most notably when the gag involves a falling boulder or rocket skates.
- The chute system in the Avatar: The Last Airbender city of Omashu counts, since it's sorta like a giant slide and rollercoaster all in one. It was even shown that Aang and Bumi used to play on them when they were kids.
- Duckman: The underground cavern in "The Road to Dendron" features a water passage which Duckman, Cornfed, and Ajax use to escape, though in a subversion, the Fakir laments: "Why did I put in that water slide?! After them!"
- Penn Zero: Part-Time Hero: The architecture of the carnival-themed Chuckle City includes a lot of roller-coaster ramps and trapezes that people can use for Ramp-rovisation.
