From the Super Mario Wiki
“Mario, I know all about your adventures around the world. You've been everywhere! And you always get the best of the bad guys. Everytime! You're the coolest! I wanna be just like you!”
Goombario is the first of Mario's party members. He made his first appearance in Paper Mario. His specialty is providing Mario with information about the various locations and enemies in the game. Thus, he is the only Party Member with two attacks which don't require FP. In the sequel, this task is carried on by Goombella (in the french version of Paper Mario, he even talks in a similar fashion to her).
 Paper Mario
When Mario falls into Goomba Village at the start of Paper Mario, Goombario and his family (Goombaria, Goompa, Gooma, Goomama and Goompapa) finds him and then he faces Jr. Troopa and they let him rest in the Toad House. When Mario falls off the balcony in Goompa's house, Goompa and Mario find a Hammer and smash through a yellow block to get back to Goomba Village. Kammy Koopa attacks the village and Mario tells them about his quest. Goompa suggests that Goombario join Mario on his adventure, and he accepts. In the field, Goombario can use his tattle to find out where Mario is and tell him about the people they meet. According to Goompapa, he is named after Mario.
He will occasionally break the fourth wall and his tattles seem to indicate a friendly rivalry with Kooper. He also stated he doesn't like eating fish, would like an Albino Dino as a pet, and that he is afraid of heights. He is also infatuated with various females in the game (namely Misstar, Vanna T., Merlee, Merluvlee, and Chanterelle).
