Endless World of Yoshis

Endless World of Yoshis, or Crazy Maze Days, is the Secret Level of the final World in Yoshi's Island: Super Mario Advance 3. It is the last Secret Level in the game, and is a difficult and time-consuming level. It contains many puzzles and difficult platforming challenges. The player must make use of the surrounding enemies to get a score of 100.

Layout
The level starts with an automatic side-scrolling section, with many small platforms and no ground to land on if the player falls. There are many enemies in important locations such as on platforms, making it hard for the player to keep up with the screen safely.

Once the player clears this section, they will enter a Warp Pipe into a castle area where the layer must fall down a long distance while avoiding many Thorns suspended in midair, which will cause the player to lose a life if hit. There is a Middle Ring at the bottom if the player survives the fall; however, it is generally wise to complete more of the level before using it, as the level has many areas which lead back to the same room, with the thorns having to be avoided again.

From here the player can choose to take the left or right path, both containing Flowers and Red Coins which are needed to get a 100% score for the level. There are rooms at the end of each path, with several choices of doors to go through. One on each end leads to the left or right area of a grassy section of the level, which has the tutorial music. This area contains 2 Flowers and several red coins. Once the player has all the collectibles from this area, they must go back to the room with the lava and midair spikes to get to a different door.

Eventually, the player can use a Key to enter a vast, lava-filled cave area. This area contains 2 more Flowers, and many pits full of spikes which can instantly defeat Yoshi. After manipulating a Chomp Rock to hold a One-Way Gate open, the player can get a key to an area where a Super Star is needed to progress.

When the player clears the cave area, they will enter one of two final sections of the level; a short flowery field that is an exact replica of Welcome To Yoshi's Island with the Goal and a pit, or if an alternative path is taken, right before the entrance to said Goal. However, it has the addition of Kamek attacking the player every few seconds, making it harder to complete. Just before the Goal is the final Flower, in a Winged Cloud.
