Chocolate Island 1

Chocolate Island 1 is a straightforward ground level in Super Mario World. This level takes place on a small island in between the Forest of Illusion and Chocolate Island. This level contains two near-identical copies of itself, aside from the placement of Dragon Coins and a 3-Up Moon, likely due to the Pipe Cannons. The most common enemies in the level are Dino-Rhinos and Dino-Torches.

Overview
Mario starts on a flat platform with a Dino-Rhino. After defeating the Dino-Rhino, Mario must jump up the two sloped platforms, avoiding the Dino-Torch. Mario lands on a hill at the top of the screen, and must run down the hill, avoiding more Dino-Rhinos and Dino-Torches. Along the way, there is a bush that gives Mario a Super Mushroom when he runs past it. The hill evens out into a flat platform at the bottom of the screen, and as Mario runs across the ground, he finds ditches and bumps in the ground with many Dino-Torches and Dino-Rhinos. Near the end of the level, there is a Flying ? Block containing a Super Mushroom or Fire Flower. Next, Mario must jump onto the higher platform and go down the staircase-like ground, avoiding another Dino-Torch. Mario then finds a Warp Pipe with a Jumping Piranha Plant and a sloped platform with a Dino-Torch. The first Dragon Coin is found above a yellow Warp Pipe.

After getting past these obstacles, Mario must enter the yellow Warp Pipe, sending Mario to the other version of the level. This connects to the Pipe Cannon that shoots Mario across a wide bottomless pit. Mario flies over a Dino-Rhino and slide down a slope to the bottom of the screen. There is a Jumping Board at the edge at the platform, which Mario must use to hit the Midway Gate at the top of the screen. If Mario does not enter the Pipe Cannon, neither the Midway Gate nor the following three Dragon Coins will be present.

The next platform has a wide ditch full of Munchers and a Chargin' Chuck. Mario must hit the Switch Block to turn the coins into Blocks, which Mario can use to cross the ditch. Afterwards, Mario has to jump up the sloped platforms, obtaining the second Dragon Coin along the way, and land on another hilly platform at the top of the screen. As Mario runs down the hill, he finds a Dino-Rhino and Dino-Torch, a Flying ? Block containing a power-up, and another hilly platform. Additionally, with the Cape Feather, Mario can fly up to an off-screen cloudy platform with a 3-Up Moon on it. Mario must jump from this platform to the next, obtaining the third Dragon Coin along the way. This platform has a ? Block containing a Yoshi Egg, spawning a Yoshi for Mario to ride. Mario must jump over the two Warp Pipes, both of which have a Jumping Piranha Plant, and jump across the bottomless pit (or walk, if Mario has activated blue ! Blocks). Above the bottomless pit, there is a ? Block containing a power-up and the fourth Dragon Coin above the block. There is a Dino-Rhino and three pipes that Mario must use to jump over the bottomless pits. Between the second and third Warp Pipes, there is a set of red ! Blocks, if Mario has activated them, over the bottomless pit.

After these three Warp Pipe, Mario finds a white Warp Pipe that allows access to a Pipe Cannon in the other version of the level, which shoots Mario across the large pit, towards the goal. The fifth and final Dragon Coin is found above a Jumping Board at the edge of the final platform, though it does not appear if Mario chooses to jump over the pit with the Cape Feather. Mario can use this Jumping Board to jump to the top of the Giant Gate.

Alternate Area
Mario must traverse the level up to the part with the three blue Warp Pipes near the end of the level. Mario must go through the second Warp Pipe, which takes Mario to a shallow water area. Here, Mario starts on a mushroom platform and a Rotating Block containing a 1-Up Mushroom. Dolphins and Porcu-Puffers make their reappearance here, and the Dolphins are needed as platforms to traverse the Porcu-Puffer-infested water. At the end of the water area, there is another mushroom platform and a Warp Pipe, which Mario must use to exit the area.

Trivia

 * If the player shoots out of the Pipe Cannon while in Caped form and holds the jump button in the process, the player can properly reach the Midway Gate in that manner based on its location in the level.
