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.

LEVEL2-1
This is a basic course that involves Wanda getting her character up a few elevators using Flip-Flop Blocks while watching out for spikes and collecting Stars. Luigi is at the top left.

LEVEL2-2
The spikes pose a more dire threat for making a mistake, but all that is necessary is for Wanda to make all the Flip-Flop Blocks in the way solid.

LEVEL2-3
This course has Rock Blocks and Jump Blocks, as well as a new obstacles which are small Pidgit birds. These little black birds are immobile and can simply be clicked away.

LEVEL2-4
This course contains a series of floating footholds with Jump Blocks and Flip-Flop Blocks suspended over a pit lined with spikes. The path is still mostly linear, with some complexity arising should the player try to obtain all the Stars.

LEVEL2-5
The character starts at the top right with the Luigi goal lying directly beneath them, but there is another spike pit. The layout suggests following a series of gradually descending Flip-Flop Blocks, which lead to Stars and Coin Blocks. The ideal path also splits between left and right; right will lead the player to a Star and a Jump Block to restart the path.

LEVEL2-6
This course is similar to LEVEL2-4, but with narrower platforms and trickier Star spots.

LEVEL2-7
This course starts out with a more complicated presentation but several previous elements in one area, but once the player breaks through some Rock Blocks and reaches the bottom, the path to Luigi becomes easier with simple Flip-Flop Blocks, although spikes are present.

LEVEL2-8
This course has tiny Flip-Flop and Rock Blocks, leading the player to do more work while avoiding several Pidgits and spikes. However, Wanda only needs to break the bottom Rock Block on the ground for her character to be able to pass through.

LEVEL2-9
This course has the same concept as LEVEL2-5, but with the goal in the bottom right, tiny Flip-Flop Blocks and more scattered Stars.

LEVEL2-10
In this cramped space, Wanda's character begins in the bottom right between two elevators. There are many elevators, Flip-Flop and Jump Blocks in here. One of the Jump Blocks leads directly to Luigi, who is on his own disconnected platform. Grabbing all the Stars requires more time and effort.
