Mailtoad

The Mailtoad is a purple Toad from Super Mario Galaxy, who is a member of the Toad Brigade. Unlike the other Toad Brigade members, Mailtoad is unique in that he periodically delivers messages to Mario in the Comet Observatory. Once his team is rescued in the Honeyhive Galaxy, he will start delivering his mail. He also goes on missions to various other galaxies with the rest of the Toad Brigade.

Super Mario Sunshine
Mailtoad first appears in Super Mario Sunshine, where he is one of the five young Toads that accompany Mario, Princess Peach, and Toadsworth on their vacation to Isle Delfino. Upon arrival, the group finds the island a mess. Soon after, the villain Shadow Mario appears and kidnaps Peach. This causes the Toads (Mailtoad among them) extreme sadness and worry. The Toads provide little help, as they spend most of their time in Delfino Plaza. Mailtoad is usually found alongside Yellow Toad and Toadsworth.

Super Mario Galaxy
After the Toad Brigade is rescued by Mario, Mailtoad will have a letter from Princess Peach containing five 1-Ups (or 20 if the player selects Luigi) every once in a while. He continues to deliver mail to Mario throughout the entire game, and will post certain messages on the Wii message board. Mailtoad will also give Mario various other letters, such as when Luigi finds a Power Star and needs rescuing, wherein he'll include a picture of where Luigi and the Star are.

Along with the other members of the Toad Brigade, Mailtoad can be seen throughout several different galaxies. He seems to have a carefree personality, as seen when Mario first finds the Toad Brigade and he sings cheerfully. Mailtoad apparently enjoys snorkeling, and will often be seen underwater. He claims to have a "Level One Snorkel-Toad Certification". In Purple Coin levels, he will appear to tell Mario if he saw any of the coins underwater or not. He also tries racing the penguins in Sea Slide Galaxy but fails to win.

When Mailtoad first introduces himself to Mario in the Comet Observatory, he refers to himself as "a mailtoad", implying that there are other Toads with this same job.

Super Mario Galaxy 2
Mailtoad stands on Starship Mario, ready to deliver letters whenever Mario returns from a Power Star mission. If Mailtoad has a letter or postcard, a small letter symbol appears over his head. Speak to Mailtoad to receive the message. Some letters are from Peach and include bonus 1-Up Mushrooms. When Mario receives an invitation for a special event or challenge, Mailtoad also presents this to the hero. Mailtoad keeps all delivered mail handy, so if Mario ever wants to revisit a past correspondence, he can just speak to the mailtoad.
