Two plays in Adventure mode

hi,

I have tried everything possible but it seems that I am not able to get my kids set up to play the adventure mode as two playes. I have the two incredible figures and I have watched many youtube videos and forums on how to set it up but for everyone it just seems to work, seemlysly. Adding to my frustration. I have the Wii console, any help will be great appreciate it!

Unfortunately with the regular Wii, only the toy box mode supports multiplayer, to an extent. Adventures are single player only.

much obliged.
I guess it's time to upgrade.
