Awazon river basin

Awazon River is main location of the game Virtual Boy Wario Land, though little of it is seen in the game. The game mainly takes place underneath the Awazon River. Wario finds himself underneath the Awazon River after stumbling upon a trap door after following three Mask-Guys taking treasure behind a waterfall.

Entry from Wario's Journal

 * ''I, Wario, have an interesting story to tell. One day during my vacation in the Awazon river basin, I landed my trusty seaplane, Bulldog, and decide to relax in the shadow of the beautiful Aldegara Waterfall. While basking in the sun, I spied some strange creatures with masks entering the waterfall. This piqued my interest!
 * ''I hurried over and followed them into the waterfall. Behind the falls there was a large cave, and in the back of the cave … there was a vault filled with a glorious mountain of treasure!!
 * ''Some of the masked creatures jumped me, but I quickly overcame them. "This treasure is all mine now!", I thought to myself and rushed in to collect the loot. Suddenly, the floor collapsed and I fell!
 * ''I found myself deep within the Earth! I was quite angry and vowed revenge on these creatures, "I will get their treasure!!!"

Trivia

 * The name Awazon River refers to the Amazon River. but the M in Amazon is flipped to a W similar to Wario's and Mario's names.
