SMBX Custom Level: Year of the Yoshi

A particularly long and challenging level, the main gimmick here is to use each Yoshi's special ability to solve puzzles and bypass obstacles and hazards.
Also, I apologize for the mouse cursor appearing midway through the video; that was the work of my cat, who insisted on headbutting me while I was recording. xD
Enjoy. :)
