Toadbert
Toadbert is a male Toad that appears in Mario & Luigi: Partners in Time. He seems to be good friends with Toadiko and says by boogity a lot. He has a blue mushroom cap and has thick glasses.
Toadbert first appeared in Yoob's belly where he was with some pink Yoshi Eggs. When Mario, Luigi, Baby Mario, and Baby Luigi come up to him he doesn't remember a thing. He just says that he remembers that he drew a drawing before he lost his memory and he remembers nothing. He also says that the picture must have made him forget stuff.
After escaping the Yoob's belly, he stays in Yoshi's Island for almost the whole game. After some time in the game Kylie Koopa falls on him making him remember everything. He then wants to warn Mario and Luigi about something.
Toadbert and Kylie go to Star Shrine, where the brothers are, and Toadbert tries to tell him something but then runs away from the Cobalt Star. Mario and Luigi don't know why he ran away and follow him.
After a while they see Toadbert on the ground with Kylie on the other side warning that there is a Elder Shrooboid (Mario first has to rub off the dirt and mud from Toadbert's Drawing). Toadbert wants to explain something to Mario, but he is then turned into a Shroob Mushroom, along with Kylie. He remains in that type of form until the ending.
He makes a reappearance in Mario & Luigi: Bowser's Inside Story. Toadbert is swallowed up by Bowser. After being freed from a closed-in area in Bowser's body, Toadbert helps the Mario Bros. by scouting out areas of Bowser's body and often appears to instruct the brothers about the functions the various areas of Bowser's body. He also has a hint booth in Toad Square inside Bowser.
