75m is the third stage of Donkey Kong and is also featured as a stage in Super Smash Bros. Brawl.
Super Smash Bros. BrawlEdit
This stage has lots of narrow scaffolding and footholds so it can feel both free and restricted to Brawl here. Items found from the original game such as the lady's purse, jack and the trouble bug.
It even has a retro Donkey Kong in his original position. 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 KO'd.
