Colossal Ruins
The Colossal Ruins is a sub-world in the Sand Kingdom that can be entered via a Moon Pipe in the starting area of the Tostarena Ruins. The level involves using Rocket Flowers to dash along the side of a large sloped section as it slowly sinks into poison.
Trivia
- It is possible to traverse the sinking ruins without activating the trigger zone that causes them to begin sinking.[1] The trigger zone only activates when Mario stands on solid ground within it, meaning its activation can be avoided by landing on the very edge of the ground closest to the screen after being ejected from the spark pylon. From there, it is possible to trickjump over the portion of ground that resides inside the trigger zone in order to access the rest of the course.
