We’ve already written about how to unlock Toad as a playable character, but how do you get the other four — Luigi, Peach, Toad, Toadette and Yoshi?
Peach is the easiest to unlock because you don’t actually have to do anything extra to get her to join your party. Once you defeat Bowser in world 6-4 of World Tour mode, she’ll become a playable character, bringing her trademark floaty jump to the game.
To unlock Yoshi, Toad and Toadette, you’ll need to build their houses in Kingdom Builder mode. Each house requires a different number of toads of varying colors to unlock. Remember, you earn different colored toads by competing in Toad Rally (and you can learn more about that in our Super Mario Run Toad Rally guide).
Yoshi is the first you’ll unlock, requiring only 30 red and 30 yellow toads. Yoshi’s flutter jump (and accompanying terrible noise) comes in very handy for some of those hard to reach coins.
You’ll unlock Luigi next when you have 150 green and purple toads each. Luigi jumps a little higher and for a longer distance than his brother Mario.
The last character you’ll unlock is Toadette. She’s a toad that has pigtails made out of mushrooms, and that’s apparently unique among toads (which either implies that it’s a deformity or she’s the only female like the Smurfs). She’s got a pretty tough requirement to meet with 200 of all five colors of toad fans. Toadette plays a lot like Toad, but she’s not Toad and that makes her better.
