This one is a stage that originated in Melee, and is based on Cranky Kong's cabin from the Donkey Kong Country series. While I didn't notice it, it stayed in Melee until the 3DS (not the WiiU) version of Smash 4. It makes its full return with Smash Ultimate.
Like most stages in the early years, there's not many hazards. Biggest thing from the stage to worry about is falling into the water. While not a dooming situation, you don't want to be careless either.
While not my favorite stage ever, I was glad to see it return this time around.
