Yoshi’s Island 2 [DS - Beta]

Yoshi’s Island DS (which was initially referred to as Yoshi’s Island 2) was originally going to be compatible with Nintendo Wi-Fi. Also, one early screenshot showcasing a battle with Big Guy the Stilted seems to suggest that Big Guy was once going to be organic, as he had no patches on him in that picture (although one patch was visible near his right foot, which may merely mean his graphics were slightly incomplete). Finally, one screenshot of an unknown origin shows a Black Yoshi traversing a flowery area with Baby Peach. The particular event illustrated in the picture doesn’t seem to be left in the final game. Baby Peach’s cry was also going to sound more adult- like. [Info from Mariowiki]
