Welcome to Concordia! A once peaceful continent held together by the prized Uni-Tree, a symbol of connection, friendship, and harmony. A long time ago, there was an attack on Concordia that destroyed the Uni-Tree and split apart the continent into 20 different islands. But no need to worry! Mario and Luigi have taken it upon themselves to reconnect the drifting islands and restore Concordia! However, that's easier said than done with Zokket and the Extension Corps around. As the brothers aim to put Concordia back together, Connie, a young Wattanist, has been growing a new Uni-Tree on Shipshape Island. This new Uni-Tree is very young, but already very big, acting as a sail for Shipshape Island. How will this story play out? Will Mario and Luigi help Connie and Snoutlet restore all of Concordia, or will Zokket and his underlings emerge victorious? Pick your character and join the adventure on whichever side you want!
