Soda Lake

Soda Lake is an underwater secret area reached by entering the secret gate of Cheese Bridge in the game Super Mario World. This level is located in World 4, Twin Bridges. Mario or Luigi will encounter a new and unique enemy (only appearing in this level), the Torpedo Ted. This underwater Bullet Bill relative (which are dropped from  Skull Boxes) can travel through walls and are always deployed in the player's direction. They cannot be defeated in any way, so it is advised to simply avoid them. When the player clears the area, they will unlock the third warp point to Star Road.

Access
To access this level, the player must use a Feather to glide their way over the first Giant Gate, or fall underneath it while riding a Yoshi to jump off, to reach an alternate Giant Gate, making it possible to access Soda Lake.

Overview
At the start Mario or Luigi will descend from a gray pipe to begin their journey. Quite suddenly a Blurp and a Skull Box appear on the horizon. Quickly climb towards the upper section of the screen as not to get trapped. Another three Blurps guard an Question Block containing either a Super Mushroom or Fire Flower depending on Mario's current state. Be wary of two approaching Torpedo Teds and a line of Blurps patrolling the bottom of the screen (note that they, unlike their Torpedo Ted allies, can indeed be killed by either a fireball or cape spin). There also the first Dragon Coin situated between two Skull Boxes, this is very risky and is not recommended if the player wishes to keep their power-up or stay alive if small.

Up ahead, a school of four Blurps make their way away from a row of descending Skull Boxes. Along with many regular coins, the second Dragon Coin near the middle Torpedo Ted. Time it so that the middle Skull Box has just fired before attempting to grab it. Making way towards the bottom of the screen, to avoid the treacherous Torpedo Teds. The next open are has a lone pillar and more pockets of Blurps (five or six this time), so swim up and continue. Drop into the nearby chasm for the third Dragon Coin, but beware the nearby Torpedo Ted which will travel through the wall to attack Mario/Luigi. That same Skull Box is accompanied by three others in this next tricky section, it is best to stay low and quickly swim up amidst whatever Torpedo Teds that may be coming Mario/Luigi's way along with three more Blurps. The fourth Dragon Coin is in plain sight right in front of yet another Skull Box, so make sure to be quick in the execution of snagging it.

Beyond said Skull Box be prepared another one higher up with two Blurps coming towards you somewhere nearby. This second Skull Box becomes the first of three in a row, all surrounding the final Dragon Coin. It is perhaps the easiest one if the player can quickly catch it before either of the upper Skull Boxes gets a chance to launch a Torpedo Ted at them. A column of four Blurps will make further passage impossible until they pass. Three more Blurps drift past as the player arrives at a passage in which they can simply walk across to avoid all the Torpedo Teds churning above them. Then simply enter the pipe, which will take the player to the surface. At this point, Mario or Luigi can just cross the Giant Gate to complete the level.
