Secrets

Alot of points

Get 500 points for Dk mountain then purchase it then play it with 1 other real player and each time you get a bunch of party points when you finish unless you get unlucky and bowser takes all your bananas (in dk mountain its bananas instead of stars)

How to get lots of party points

Well you need to go into the main menu and select party mode. Then have 2 players with no COMs. Select any map EXCEPT toad road. In the end of the game you should at least have 45ministars each. Added up all the bonus stars and at the end you should get more than 200 party points. Hope this helps!
