Neo Greo is identifiable by its green hex icon in the selection wheel of both the Main Game and Rainbow Run. Similar to the others, the stages can be played in any order, but a Boss Game will begin after completing all three. And lastly, 9 medals are offered in the main game, but 18 medals are available in the Rainbow Run Line Trial and Time Trial challenges. Neo Greo's name is a pun on "green".
