6. Which Mario series character moved from a playable character to an NPC in "Mario Party 6"?
From Quiz "Mario Party 6": Partying Day and Night
Answer:
Donkey Kong
Sorry, you can no longer play as DK after "Mario Party 4". From what I hear, DK was no longer playable in "Mario Party 5", but I can't speak from experience on that one, since I've never played that game. DK now appears when a player lands on a DK Space on the board. He occasionally gives the player free coins or even a Star, but usually he draws all players into one of three special DK Mini-Games ("Tally Me Banana", "Pier Factor", and "Banana Shake"), in which players try to collect as many bananas as possible. Each banana is worth one, two, or three coins, depending on DK's roulette. DK also appears dispensing Stars on Castaway Bay and Clockwork Castle.
Toad first became a playable character in "Mario Party 5". In previous games in the series, Toad gave out Stars and appeared in various Mini-Games.
Yoshi and Wario have been playable characters in the "Mario Party" series since the beginning, and are still playable.
