The Trophy Collector is a stage found in Super Smash Bros. Melee's Classic Mode. It consists of a large cup made of rings, with trophies falling from the sky, which must be knocked into the cup. There are also two, smaller, floating platforms on the sides. The top ring of the "cup" acts like a floating platform, while the bottom section can be walked through.
The Trophy Collector is available through hacking, though when used in Debug Mode, it will crash when a trophy appears. This can be avoided via other hacks.
