Toad
When Toadsworth is under an umbrella infront of the crate place, talk to him. Then Jump on his his head for at least 5 minuites. If you jumps on his head longer, that's ok. Then talk to him again. He'll ask you what your favorite color is. Chose the color you want the playabale toad to be. Then die or collect a shine sprite in delfino. when you come back, you'll be a backwards toad, as in he faces the wrong way. He'll be the color you chose, and he'll have fludd on his head. He sounds like Mario and when he dies or gets a shine sprite, he turns into Mario. This is because you activated a scrapped method to get a new playable character they coulden't completly delete. Once you leave delfino, you'll be Mario again.
