Endless World of Yoshis

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

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

Once the player clears this section, they will go down a Warp Pipe into a castle area where Yoshi must fall down a long distance while avoiding many spikes suspended in midair - these spikes are the type that instantly cause Yoshi to faint. There is a Middle Ring at the bottom if Yoshi survives the dangerous 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 spikes 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 essential to get a 100% score for the level. There are rooms at the end of each path which have several choices of doors to go through. One on each end leads to the left or right area of a grassed section of the level which has the tutorial music. That contains 2 Flowers and several red coins. Once the player has all the collectibles from this area, he or she must go back to the long 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 very large area contains 2 more Flowers, and many pits full of spikes which cause instant Game Over to Yoshi. After carefully manipulating a Chomp Rock to hold a One-Way Gate open, Yoshi can get a key to an area where a Super Star is needed to progress.

When Yoshi eventually clears the large cave area, he will enter the final section of this very long level; a flowery field that is an exact replica of the final section of Welcome to Yoshi's Island. However, it has the addition of Kamek attacking Yoshi every few seconds, making it much more dangerous. Just before the Goal (end of the level) is the final Flower, in a Winged Cloud.
