Yosu Ko

Yosu Ko (ヨス湖, or Yosu Lake) is the second stage found in Mario & Wario. Less traps are present in this world, so it is still a tutorial in some ways. Yoshis are seen relaxing in the background with their children, oblivious to the events unfolding in the foreground; as such, this area may be located on Yoshi's Island. Wario uses half of a cracked Yoshi Egg to subdue the character.
