Inevitable Tragedy

The Inevitable Tragedy is a treasure in, that can be found in The Burning Sky area. It is actually a Super Mario Bros. Nintendo Entertainment System cartridge. It is about five times Captain Olimar's width and height, and looks just like the cartridge in real life.

Collecting the treasure
After the White Spectralid cutscene, you will bounce on a Bouncy Mushroom. Instead of proceeding to the right, you have to go to the left. Going towards this direction leads to a hole, serving as a nest for Crystalline Crushblats, with the treasure behind it, partially buried.
