Soda Lake

Soda Lake is an underwater level that can be reached by the Cheese Bridge in the game Super Mario World. To get there, Mario must get a Feather in the level Cheese Bridge Area and glide his way over the first Giant Gate, to reach an alternate Giant Gate, making it possible to access Soda Lake. Once Mario beats the level, he can open up a path to Star Road. Additionally, Soda Lake is the only level with the enemy known as Torpedo Ted. Blurps also appear in this level.

It is not known if Soda Lake is actually soda. (Cheese Bridge isn't made of cheese, for example, and neither is Butter Bridge made of butter.) Since the water is clear, it is either plain water or soda water (carbonated water), not soda pop. It could actually be Salt Water since it is connected to the sea.

Appearances in Other Media
Though never named as such, what could possibly be Soda Lake appeared in the episodes "King Scoopa Koopa" and "Mama Luigi" of the Super Mario World animated series. Like Soda Lake, this body of water had Torpedo Teds, Rip Van Fish and Dolphins in it.
