Did you know that there are 4 secret characters to unlock in Super Mario Party? Thankfully Prima Guides has a video tutorial on how you can nab each one as you progress through the game’s many modes and mini-games.
** Important Note ** The only way to unlock the characters instantly is to find them in the overworld / plaza as soon as you meet the criteria.
Donkey Kong - Play the River Survival game 3x taking the different path each time.
Diddy Kong - Complete World 2 of Challenge Road.
Pom Pom - Complete World 5 of Challenge Road.
Dry Bones - Completely random….. ¯\_(ツ)_/¯
Also remember the final game board Kamek’s Tantalizing Tower is completed by simply finishing the other boards.
