Goombella

Goombella is Mario's first partner in Paper Mario: The Thousand-Year Door.

When Mario arrives at Rogueport at the beginning of the game, he sees a Goomba girl being attacked by Lord Crump. Mario helps her and defeats Lord Crump. Goombella thanks Mario and joins his party. She possesses most of the same abilities Goombario has outside of battle in the first Paper Mario.

Her Tattle ability gives the player helpful information on places, people, enemies, etc. Like Goombario's summaries, Goombella inserts her own little opinions in her descriptions. For example, she disses Beldam's snotty attitude, shows signs of resentment upon reading the "underlings of underlings" comment her book says regarding Goombas, and points out that it's nice to have access to a bathroom now and then (that's a field-only one, stated in the Glitz Pit's major league locker room, where the bathroom is always occupied).

Goombella also has an odd tendency of breaking the fourth wall. In Glitzville she mentions how far Cheep-Cheeps have come since Super Mario Bros., and in Twilight Town she says that if there weren't people like the gatekeeper in every town games would be beaten too easily. Both times she stops abruptly after she says the comment, seeming to point out that game characters know about the Fourth Wall but aren't supposed to talk about it.

Her name is probably a portmanteau between "Goomba" and the female name "Isabella". Goombella's name in the Japanese version of the game is Kurisuchiinu (Pronounced Ku-Ri-Su-Ti-Nu), which comes from both Kuribo, the Japanese name for Goomba, and the female name "Christine".

At the end of the game, Goombella begins to tell Mario that she is in love with him, but then changes her mind.

She becomes Professor Frankly's lab assistant at the very end of the adventure.
