Vanilla Secret 1

Vanilla Secret 1 is a secret level in the Vanilla Dome of Super Mario World. It is when the player must jump up hills, in a cave, while avoiding Koopas and Football Koopas. If the player makes his/her way up the hills to the exit, he will unlock a Warp Pipe leading to Vanilla Secret 2 (which is played outside the vanilla dome).

Overview
To start, Mario must first jump over the hills, avoiding the Koopas in the way, and jump to the right. Next, the player must jump on the bouncy platforms to get to higher ground and to reach a nearby pipe, with three blocks above it. When Mario hits the middle block, a Vine will pop out, going up to a Dragon Coin and a block containing another Vine. After Mario climbs that Vine, he must time his jump on a Jumping Board to reach a platform, while avoiding a few Paratroopas. After this, the player can use another Jumping Board to reach two more Dragon Coins. When the player jumps on more of the bouncy platforms to a Warp Pipe, he will reach the Giant Gate, which opens up a Warp Pipe on the map, taking the player to Vanilla Secret 2.

Secret Path
Mario can reach the Secret Path either by beating the Blue Switch Palace (In the Forest of Illusion), or by using a Cape Feather. When Mario is at the first Jumping Board, he must carry it and go to the right and place it on the blue ! blocks, jumping on it to reach a Warp Pipe (Cape Mario can run and jump to the Pipe). Past the pipe is the Gate, which lets Mario go to the Star Road.
