How about a plane racing mini-game? Sort of plays like the bumble bee mini-game from Mario Party 6, but instead you fly around Wuhu Island.
Bingo battle-players take turns picking random bingo balls from a bingo spinner(numbers are hidden), and at the beginning of the game the players take turns picking out a bingo card
That's all I have for now...I'm about to do the Lost Levels Podcast...Hopefully I'll post more later today(but don't count on it)...Sorry(I have a wedding to go to also today)
