Escape from the woods!
From the Super Mario Wiki
Escape from the woods! is the second story of chapter two in the game Wario Land II. Like the previous level it is set in a forest area. Many ball-throwing Penguins roam this area so the player should be careful to avoid them. If one of their attacks hit Wario, he will become dizzy and controlling him becomes much harder. To restore his senses the player has to guide him to any body of water.
Hidden treasure: Dagger
The hidden treasure of this level, the Dagger, is located right above the goal door. In order to reach it the player must use the slope on the left side of the room and jump up to a ledge (a trail of coins will indicate the right spot to jump). Wario will then smash through a row of bricks that block the way to the treasure door.
