This is EC2Joshi's fifth custom track. It takes place in a grassland with an underground section.

In May 2012, the author released a "special edition" of the track. This completely changes how it plays by including sections of tracks the author has previously made, including Bowser's Castle 1, Mushroom Land and Ruin Labyrinth. It is much longer to complete than the original version due to the additions.

Custom Track Distributions

This track is part of the following Custom Track Distributions:


In RC1 to RC5.2, Bowser's Castle 1 can be found as an Easter egg. It can be accessed by driving toward a few grass hills at the top-left part of the track. A part is not fenced, meaning the player can access within it and access the secret area. Video
