Do you know how to open the Bowser Party Tent at Mario Party 8 for the Nintendo Wii?

Question

I've finished the other five tents with my sister already and we have over 100 play cards, but we didn't find the Bowser Party Tent at the store. What do we have to do to open that tent?
Also to increase your chance of winning 10 pts for this question, please let us know how to get the extra characters. Thank you!

Answer 1

To open Bowser's party tent and the extra characters, you have to play Star Battle Arena all the way through. Once you have beaten it, it will be available in the Party Tent. I have the game and had to go through the Star Battle Arena to get it. Have fun! :)

Edit: You have to go through Star Battle Arena twice to unlock the characters.
