The Lake Shore
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
The Lake Shore, a Subspace Emissary level, is from SSBB.
Here, Kirby ditches Peach/Zelda, only for her to get shot by Bowser. Then, False Bowser decomposes into the ground and reaches the princess, rendering her therefore as False. Link attacks the False Princess, as Yoshi follows him. But then Pit and Mario overhear them, and they fight. After one of the teams is turned into a Trophy, King Dedede drives by in a carrier(which he stole from Wario earlier) and snatches the defeated trophies. Just then, Kirby turns the defeated team back into humans. Pit pops Dedede's tire with his bow. So, the quintet of heroes chase Dedede.
