75m is a stage in Super Smash Bros. Brawl.
This stage has lots of narrow scaffolding and footholds so it can feel both free and restricted to Brawl here. Items found from the orignal game such as the lady's purse, jack and the trouble bug.
It even has a retro Donkey Kong in his orignal postition. If he's dark looking, he doesn't do anything but when he's bright then whoever's touching him will get damaged and possbily KOed.
