Dr. Toadley

Doctor Toadley is a Toad that appears in Mario & Luigi: Bowser's Inside Story. He resides in Toad Town in the Toadley Clinic. He is said to know "all there is to know about the Mushroom Kingdom" (he himself claiming that he knows everything), obtaining information from his crystal ball. He also has a tendency to ask and answer his own questions.

He is first mentioned at the beginning of the game, during the meeting held in Peach's Castle about the blorbs outbreak. As he was too busy helping afflicted patients, he sent his intern to the castle in his stead.

Later in the game, after Fawful obtains the Dark Star and blocks off Peach's Castle, Mario and Luigi go to Doctor Toadley to figure out what to do about it. After Bowser shows up and is defeated, Toadley tells them about the Star Cures. He tells the group that the first Star Cure is in Dimble Wood, held by Durmite. However, Mario and Luigi remember defeating Durmite already inside Bowser, and go off to find the Star Cure.

After Mario and Luigi collect the first Star Cure, Doctor Toadley, through Birdley, informs Mario, Luigi, and Bowser that the second sage is Kuzzle at Plack Beach (though his Star Cure was taken by Bowser at some earlier time and is in the treasure room at Bowser's Castle). He also informs Bowser that Mario and Luigi already have the first Star Cure.

After obtaining the second Star Cure, Mario and Luigi return to Toadley Clinic, where Doctor Toadley tells them the location of the third and final Star Cure, which is high up in the air above Plack Beach. Before the brothers leave, Doctor Toadley tests Mario and Luigi's breathing to see if they are fit for high altitudes, where the air is thinner. Mario passes, and after Luigi fails, he tries again, this time breathing so hard the machine malfunctions and breaks the clinic's ventilation system. After testing, Doctor Toadley allows Mario and Luigi to get the final Star Cure while he fixes the machine.

After Mario and Luigi get the third and final Star Cure, they once again return to Toadley Clinic. Toadley takes the three Star Cures and combines them into the Miracle Cure, which he then immediately uses to cure the blorbs before giving it to the brothers. He also has his intern give Mario and Luigi a full set of Attack Pieces, allowing them to use the Special Attack Mighty Meteor.

In Mario & Luigi: Superstar Saga + Bowser's Minions, Doctor Toadley replaces Psycho Kamek from Mario & Luigi: Superstar Saga.

Trivia

 * Doctor Toadley, from the back, slightly resembles Merluvlee from Super Paper Mario.
 * Doctor Toadley has a tendency to answer his own questions ("Is this good timing? It is.").
 * Not counting Toadsworth the Younger, Doctor Toadley is one of the few Toads to debut in a Mario & Luigi game and have official artwork. The other one is Toadbert. However, Toadbert only got official artwork in Mario & Luigi: Bowser's Inside Story, so Doctor Toadley is the only Mario & Luigi exclusive Toad to get official artwork in his debut game.
